0-3 Months: Welcome to the World
Welcoming your baby into the world is an unforgettable experience, no matter how they arrived—whether through a natural birth, a C-section, or an assisted delivery. In these first few months, your life and your baby’s life will change in countless ways as you both adjust to this new phase. Here’s what to expect and how to navigate this delicate and exciting time.

Hospital Treatments
When your baby is born, they will undergo several routine treatments and tests. Some are required, while others are optional, allowing you to make informed decisions that align with your preferences. It’s important to note that the following are essential for optimal newborn care. Here’s what you can expect:
Apgar Test
- Purpose: Conducted at one minute and five minutes after birth, the Apgar test evaluates your baby’s physical condition based on five criteria: appearance (skin color), pulse (heart rate), grimace response (reflexes), activity (muscle tone), and respiration (breathing rate and effort).
- Why It Matters: The Apgar score helps medical staff quickly assess if your baby needs immediate care, such as extra oxygen or other interventions.
Eye Ointment
- Purpose: Antibiotic ointment is applied to the baby’s eyes to prevent infection from bacteria the baby may have been exposed to during delivery.
- Why It Matters: It’s a preventative measure against infections like gonorrhea, which can cause blindness in newborns.
Vitamin K Injection
- Purpose: This injection is given to help prevent serious bleeding in newborns, as babies are born with low levels of Vitamin K, which is crucial for blood clotting.
- Why It Matters: It reduces the risk of a rare but dangerous condition called Vitamin K Deficiency Bleeding (VKDB).
Newborn Screening Test (Heel Stick Test)
- Purpose: A small blood sample is taken from the baby’s heel (known as the heel stick test) to screen for genetic, metabolic, and hormone-related conditions.
- Why It Matters: Early detection of conditions like phenylketonuria (PKU) or congenital hypothyroidism can lead to treatments that improve long-term health outcomes for your baby.
Hepatitis B Vaccine
- Purpose: This is often given within the first 24 hours of birth to protect your baby from Hepatitis B, a potentially serious liver infection.
- Why It Matters: Early protection helps safeguard your baby from the disease, which can be passed from mother to baby during birth or from other sources later in life.
Hearing Test
- Purpose: This simple, painless test assesses your baby’s hearing ability.
- Why It Matters: Early diagnosis of hearing issues allows for early intervention, which is crucial for language and cognitive development.
Bilirubin Test
- Purpose: This test measures the level of bilirubin in your baby’s blood to determine if treatment is needed. This could involve either a blood sample (also commonly from a heel stick) or a non-invasive device that measures bilirubin levels through the skin (known as transcutaneous bilirubinometry).
- Why It Matters: If bilirubin levels are too high, it could lead to serious complications like brain damage. In mild cases, jaundice can resolve on its own with time or through increased feedings. In more severe cases, treatment options include phototherapy (light treatment).

First Pediatrician Appointment
Typically, your baby’s first doctor’s visit will be about 2 days after birth. At this appointment, the pediatrician will:
- Check your baby’s weight and growth
- Examine their overall health and behavior
- Address any feeding issues
- Discuss jaundice, sleeping patterns, and how to care for their umbilical cord stump
Please note that this appointment is non-negotiable, but will be very taxing for the new parent. Try to dress as comfortably as you can, and either bring someone with you or see if you can send another guardian to attend the appointment so that you can rest. Bring a list of questions.
Appointments in the First 3 Months
You can expect multiple check-ups within the first three months. These will include regular monitoring of your baby’s growth, development, and feeding habits:
- 2-week check-up: Weight gain, feeding, and diaper output.
- 1-month check-up: Another growth check and potentially the first round of vaccines, such as the second dose of the Hepatitis B vaccine.
- 2-month check-up: Your baby will receive several vaccinations, such as:
- DTaP (diphtheria, tetanus, and pertussis)
- Hib (Haemophilus influenzae type b)
- Polio
- Pneumococcal vaccine
- Rotavirus
Optional vaccines, like the flu shot (if flu season), may also be discussed.
Visitors and Hygiene
It’s natural to want to share your joy with friends and family, but newborns are more vulnerable to illness. Here are a few tips:
- Handwashing: Encourage visitors to wash their hands before handling the baby.
- No Kissing: Politely ask visitors to avoid kissing your baby, especially on the face, to prevent the spread of germs.
By following these guidelines, you can keep your baby safe while still allowing loved ones to visit.
Sensory Development: Seeing, Hearing, and Feeling
At birth, your baby’s senses are already working, but they’re still developing:
- Vision: Newborns can see up to 8-12 inches away, mainly black, white, and shades of gray. By 2-3 months, they’ll start seeing more colors and tracking objects.
- Hearing: Babies can hear well from birth and will respond to familiar voices, especially their parents.
- Touch: Your baby will enjoy being held and comforted, which helps them feel safe and secure. Skin-to-skin contact is incredibly soothing during this time.
Milestones: 0-3 Months
While every baby is different, here are some general developmental milestones to look out for in the first few months:
- 1 Month: Brief moments of eye contact, recognizing voices, and starting to lift their head during tummy time.
- 2 Months: Smiling at familiar faces, cooing sounds, and moving arms and legs more actively.
- 3 Months: Better head control, tracking objects with their eyes, and showing excitement through facial expressions and kicking.

Physical and Motor Development
During the first three months, your baby’s physical growth and motor development are rapid as they begin to explore their body and surroundings. Key areas of growth during this period include:
Head and Neck Control
By the end of the third month, most babies develop stronger neck muscles, which allows them to begin holding their heads up for short periods. This is an exciting milestone that lays the foundation for further physical development. You’ll likely notice your baby lifting their head briefly during tummy time or when being held upright.
Tummy Time: A Crucial Activity
Tummy time is one of the most important exercises you can introduce early on. It not only helps your baby develop neck and head control but also strengthens the muscles in their arms, back, and legs, which are essential for future milestones like rolling over, sitting up, and eventually crawling.
Here are some tips to encourage and make tummy time enjoyable for your baby:
- Start Early: You can introduce tummy time as early as a few days old, for 1-2 minutes per session, working up to longer sessions as your baby gets stronger. Try to aim for a total of 20-30 minutes of tummy time each day by the time they are 3 months old.
- Make It Fun: Use toys, mirrors, or colorful books to grab your baby’s attention while they’re on their tummy. You can also lie down in front of them and talk or sing to make tummy time a positive experience.
- Break It Up: Don’t feel pressured to do tummy time all at once. Spread it out in short bursts throughout the day. After each diaper change or nap is a great time to get some tummy time in.
- Positioning: In the beginning, tummy time can be challenging for babies. Place your baby on a soft surface like a play mat or blanket and, for extra comfort, try using a rolled-up towel under their chest for support. You can also do tummy time on your chest instead of the floor!
- Interactive Time: Join in! Get down on the floor at eye level with your baby to offer encouragement. Babies love faces, and having you nearby helps to keep them engaged and happy during tummy time.
Benefits of Tummy Time
Tummy time encourages your baby to build strength in their upper body, which is critical for hitting motor milestones down the road. Regular tummy time also helps prevent conditions like positional plagiocephaly (flat head syndrome) that can develop if babies spend too much time lying on their backs.
By consistently encouraging tummy time, you help your baby develop essential motor skills, laying the foundation for rolling over, crawling, and even walking.
Premature Babies and Development
If your baby was born prematurely, it’s important to know that their developmental milestones may differ from babies born at full term. This is completely normal and nothing to worry about—premature babies typically reach milestones later than their peers, but with time, they often catch up. Premature or not, all babies develop at their own unique pace, so it’s key to remain patient and trust the process.
Healthcare providers often use a “corrected age” for premature babies, adjusting developmental expectations based on their due date rather than their actual birth date. For example, if your baby was born two months early, their milestones will likely align with babies who are two months younger.
Feeding Your Baby: 0-3 Months
Whether you choose breastfeeding, formula, or both, what matters most is that your baby is healthy and thriving. It’s okay to make adjustments to your feeding method as your baby grows or as your circumstances change. Consulting with your pediatrician is always a good step when making decisions about your baby’s feeding routine.
Here’s a helpful chart outlining how much breastmilk and formula a baby typically consumes from 0 to 3 months:
| Age (Weeks) | Breastmilk (Approximate Amount)** | Formula (Approximate Amount)** |
|---|---|---|
| 0-1 Week | On demand, typically 1-2 oz per feeding every 2-3 hours. 8-12 feedings per day. | 1-2 oz per feeding every 2-3 hours. 6-10 feedings per day. |
| 2-4 Weeks | On demand, typically 2-3 oz per feeding every 2-3 hours. 8-12 feedings per day. | 2-3 oz per feeding every 3-4 hours. 7-8 feedings per day. |
| 1-2 Months | On demand, typically 3-4 oz per feeding every 2-3 hours. 7-9 feedings per day. | 3-4 oz per feeding every 3-4 hours. 6-8 feedings per day. |
| 2-3 Months | On demand, typically 4-5 oz per feeding every 2-3 hours. 6-8 feedings per day. | 4-5 oz per feeding every 3-4 hours. 5-7 feedings per day. |
Formula: Formula-fed babies typically follow a more structured feeding schedule, with slightly fewer feedings per day.
Switching Between Breastfeeding and Formula
Many parents wonder if it’s okay to switch between breastmilk and formula, or do both. The answer is yes—it’s perfectly fine to:
- Switch from Breastfeeding to Formula: If you choose to transition from breastfeeding to formula, do it gradually to allow your body to adjust and avoid issues like engorgement. Also, this gradual transition gives your baby time to adapt to the new formula.
- Switch from Formula to Breastfeeding: If you initially started with formula and decide to breastfeed, it’s still possible, though it might take time to build up your milk supply. Consulting with a lactation consultant can help ease the process.
- Combination Feeding: Many parents successfully combine breastfeeding and formula feeding. This is sometimes called “mixed feeding” or “combi-feeding.” It allows flexibility, especially for working parents, and ensures your baby is well-nourished even when you’re not able to nurse.
Understanding Formula Types
When it comes to feeding your baby, there are several different types of formula available. Choosing the right one depends on your baby’s needs and how they respond to each option. Whether you’re formula feeding, breastfeeding, or doing both, it’s important to know how to handle any complications and how to properly store and manage breast milk.
Types of Formula
- Cow’s Milk-Based Formula:
- Overview: The most common type, modified to resemble breast milk and suitable for most babies.
- When to Use: For healthy infants without any specific dietary needs or allergies.
- Soy-Based Formula:
- Overview: Made from soy protein, this formula is lactose-free.
- When to Use: Good for babies with lactose intolerance or families following a vegetarian or vegan lifestyle.
- Hypoallergenic Formula:
- Overview: Designed for babies with allergies or intolerances to cow’s milk protein. The proteins are broken down into smaller parts to reduce allergic reactions.
- When to Use: For babies diagnosed with a milk allergy or sensitivity.
- Lactose-Free Formula:
- Overview: Contains no lactose but still made from cow’s milk proteins.
- When to Use: For babies with lactose intolerance, although this is rare in infants.
- Specialty Formulas:
- Overview: These include premature infant formulas, anti-reflux formulas, and others designed for specific medical needs.
- When to Use: Only under the guidance of your pediatrician, particularly if your baby was born prematurely or has specific health conditions.
Formula Feeding Complications
- Gas and Bloating: Some babies may become gassy or bloated after formula feeding. This could be due to the type of formula or how the baby is fed (e.g., swallowing air from the bottle).
- Constipation or Diarrhea: If your baby’s stools become hard or watery, it may indicate that the formula isn’t agreeing with them. You may need to switch to a different type.
- Spit-Up and Reflux: Spitting up small amounts is normal, but excessive spit-up might indicate reflux. Special anti-reflux formulas or feeding adjustments may be recommended by your doctor.
- Allergic Reactions: Signs of an allergy include hives, vomiting, diarrhea, or blood in the stool. If your baby shows these symptoms, a hypoallergenic or specialty formula may be necessary.
Storing Breast Milk
If you’re breastfeeding and pumping, proper storage is crucial to ensure the milk remains safe for your baby.
- How to Store Breast Milk:
- Room Temperature: Breast milk can be kept at room temperature (77°F or 25°C) for up to 4 hours.
- Refrigerator: Store breast milk in the back of the refrigerator at 40°F (4°C) for up to 4 days.
- Freezer: Milk can be frozen at 0°F (-18°C) or below. It can be stored for up to 6 months in a standard freezer, and 12 months in a deep freezer, though using it within 6 months is ideal.
- Pumping Between Feedings:
- Pump between feedings, ideally about an hour after nursing or at least 30 minutes before the next feeding, to build up a milk supply.
- If you’re combining breastfeeding and bottle feeding, it’s helpful to maintain a consistent pumping schedule to avoid engorgement and ensure continued milk production.
- When to Throw Breast Milk Out:
- Thawed Milk: Once breast milk is thawed, it should be used within 24 hours and should not be refrozen.
- Leftover Milk: If your baby doesn’t finish a bottle of breast milk, discard it within 1-2 hours.
- Expired Milk: Follow the storage guidelines for refrigerating and freezing milk. If you’re unsure of the age or condition of the milk, it’s best to discard it.

Diaper Needs and Sizes
During the first three months, expect to go through a lot of diapers. On average, newborns wet or soil 8-12 diapers per day (that’s 720-1,080 diapers by 3 months!) Here’s a breakdown of what you’ll likely need in terms of size:
- Newborn size: These will be your go-to for the first few weeks, especially for babies under 10 pounds.
- Size 1: As your baby gains weight, you’ll likely switch to Size 1 diapers around 1 month old, which generally fit babies between 8-14 pounds.
Having both newborn and size 1 diapers on hand is ideal to ensure you’re ready for growth spurts.
Choosing the Right Diaper Brand for Your Baby
Selecting the right diaper brand depends on your baby’s needs, budget, and lifestyle. Whether you prioritize eco-friendliness, comfort, or absorbency, finding the best fit may require some trial and error. Here’s a list of popular diaper brands to help you get started.
- Pampers – Soft, high absorbency, great for newborns.
- Huggies – Leak protection, contoured fit, good for overnight.
- The Honest Company – Eco-friendly, non-toxic, sustainable.
- Luvs – Budget-friendly, reliable absorbency.
- Seventh Generation – Plant-based, chemical-free, eco-conscious.
- Bambo Nature – Biodegradable, gentle on sensitive skin.
- Mama Bear (Amazon) – Affordable, decent absorbency.
- Millie Moon – Premium softness, chemical-free, highly absorbent.
Using Cloth Diapers
Opting for cloth diapers offers eco-friendly, cost-effective, and skin-friendly benefits. Unlike disposables, which contribute to landfill waste, cloth diapers can be reused, significantly reducing environmental impact. Though the upfront cost may be higher, they save money over time, especially if used for multiple children. Made from natural materials like cotton or bamboo, they are gentler on a baby’s skin, reducing the risk of diaper rash.
However, cloth diapers require more frequent changes and regular washing, which can be time-consuming. The bulky fit may also necessitate sizing up baby clothes, and disposables are often more convenient for travel. Some parents use a mix of both for flexibility.
There are various cloth diaper types, such as prefolds, all-in-ones, and pocket diapers, each offering different levels of convenience and absorbency. To make cloth diapering more sustainable, energy-efficient washing methods and eco-friendly detergents can be used.
Ultimately, choosing cloth diapers depends on your lifestyle and preferences. Many parents find a hybrid approach—using cloth at home and disposables on the go—strikes the right balance between convenience and sustainability.
Bonding with Your 0-3 Month Old
Bonding with your baby is crucial for their emotional development. Even though they seem sleepy, newborns are absorbing their environment. Here are some simple ways to strengthen your connection:
- Reading and Singing: Your voice is soothing, and babies love hearing it. Reading or singing helps them get familiar with language patterns and provides comfort.
- Taking Walks: Fresh air and gentle movement while walking or in a stroller offers new sensory experiences and promotes bonding.
- Professional Photos: Capture precious moments with professional photos to cherish early bonding time.
- Toys: Introduce soft rattles or high-contrast toys to stimulate your baby’s developing senses.
- Rocking: Gentle rocking or bouncing mimics the womb, soothing your baby and enhancing emotional attachment.
Bonding with Siblings
Introducing your baby to older siblings is an important step in fostering a loving family connection. Here are some tips to encourage sibling bonding:
- Involve Siblings in Care: Let older siblings participate in small tasks, like bringing diapers or holding the baby (with supervision). This makes them feel included and helps them form a connection.
- Praise Sibling Interactions: Celebrate moments when siblings interact positively with the baby, reinforcing that they play an important role in the baby’s life.
- Encourage Gentle Play: Show older siblings how to interact gently, like touching the baby’s feet or showing them toys. It helps them understand their new sibling while promoting a bond.
- Read Together: Have the older sibling read or sing to the baby. It allows them to feel involved and gives them a special way to bond.
Taking time to build these bonds early on fosters a loving and supportive family environment for both your baby and their siblings.
Bath Time Tips
Bath time can be a relaxing and enjoyable experience for both you and your baby. However, it’s important to approach it with care to ensure safety and comfort:
- Frequency: Newborns don’t need daily baths. Two to three times a week is usually enough, with regular wipe-downs between baths.
- Temperature: Make sure the water is lukewarm (around 100°F or 37°C). Test the temperature with your elbow or wrist to ensure it’s comfortable for your baby.
- Bathing Essentials: Gather all the essentials before you start, such as mild baby soap, washcloths, a baby towel, and a soft brush for their scalp.
- Cradle Cap: This is a common, harmless condition that causes a baby’s scalp to have flaky patches. Gently washing their head and using a soft brush can help clear it up.
- Safety First: Never leave your baby unattended in the bath, even for a moment. Always keep one hand on them, as they can easily slip.
Sleep and Safe Sleeping Practices
Sleep is vital for your baby’s growth and development, but newborns’ sleep patterns can be unpredictable. During the first three months, babies typically sleep 14-17 hours a day, but they wake frequently for feeding and comfort. Establishing safe sleeping habits early on is essential for their well-being. Whether you choose crib training or co-sleeping, understanding safe sleep guidelines and your baby’s needs will help ensure restful nights for both you and your little one. Here’s everything you need to know about sleep patterns, white noise, and when to start sleep training.
Sleep for Babies Aged 0-3 Months
| Age Range | Total Sleep per Day | Sleep Duration per Nap | Nighttime Sleep (With Waking for Feedings) | Notes |
|---|---|---|---|---|
| 0-1 month | 14-17 hours | 2-4 hours | 2-4 hours | Babies wake every 2-3 hours for feeding; no fixed sleep schedule yet. |
| 1-2 months | 14-16 hours | 3-4 hours | 3-4 hours | Babies may start sleeping slightly longer stretches at night. |
| 2-3 months | 14-16 hours | 3-5 hours | 4-6 hours | Sleep becomes a bit more consolidated, but frequent waking continues. |
- Crib Training vs. Co-Sleeping: It’s important to choose what works best for your family. Co-sleeping can offer convenience, but it comes with safety risks, so it’s vital to follow guidelines if you choose this route. Crib training, on the other hand, helps establish a separate sleeping space, which is safer but may take some time to get used to.
- Sleep training typically becomes more effective after 4-6 months, once babies can sleep for longer stretches at night and develop more consistent sleep patterns. Before this age, it’s natural for babies to wake frequently for feeding and comfort.
- Safe Sleeping Practices (Sleep Safety Seven): To reduce the risk of sudden infant death syndrome (SIDS), it’s essential to follow safe sleep guidelines. If you choose to co-sleep, follow the “Safe Sleep Seven”:
- No Smoking – Ensure a smoke-free environment.
- Sober Caregivers – Caregivers should be alcohol and drug-free.
- Breastfeeding – Breastfeeding reduces the risk of SIDS.
- Healthy Baby – Ensure your baby is healthy and full-term.
- Baby on Back – Always place your baby on their back for sleep.
- Safe Surface – Use a firm mattress with no loose bedding, pillows, or toys.
- No Heavy Layers – Avoid over-bundling your baby with heavy blankets or clothes during sleep. Using a sleep sack is a safer alternative.
- White Noise: Using white noise can help your baby sleep by mimicking the sounds of the womb. It can block out household noises and help your baby feel more secure during sleep.
Common Newborn Upsets & Remedies
Newborns often face a variety of skin and health issues in their first few months. From diaper rash to colic, understanding how to treat these conditions will help keep your baby comfortable and healthy. Here’s a guide to some of the most common newborn upsets and how to handle them.

Eczema
- What It Is: Eczema causes dry, red, and itchy patches of skin, often appearing on the face, scalp, or body.
- Causes: Genetic factors, environmental allergens, and skin irritants from soaps or detergents can trigger eczema.
- Treatment: Use fragrance-free moisturizers and mild, soap-free cleansers. Severe cases may need medicated creams prescribed by a pediatrician.
Baby Acne
- What It Is: Small red or white bumps on the face, caused by maternal hormones passed during pregnancy.
- Treatment: Wash gently with water and mild soap once a day. Baby acne clears up on its own in a few weeks, so no special treatment is required.
Diaper Rash
- What It Is: Red, swollen irritation on the diaper area due to prolonged moisture or friction.
- Treatment: Change diapers frequently, apply diaper rash cream with zinc oxide, and give your baby’s skin some air time. Opt for fragrance-free products to reduce irritation.
Colic
- What It Is: Intense, prolonged crying in an otherwise healthy baby, often occurring in the evening.
- Causes: Unknown, though some theories include gas or overstimulation.
- Treatment: Swaddling, rocking, and white noise may help soothe your baby. If colic persists, consult your pediatrician for guidance.
GERD (Gastroesophageal Reflux Disease)
- What It Is: Frequent spit-up or vomiting due to stomach acid flowing back into the esophagus.
- Symptoms: Excessive spit-up, irritability, and poor feeding.
- Treatment: Feeding smaller amounts more frequently, keeping the baby upright after meals, and using reflux-safe formulas. In severe cases, medication may be needed.
When to See a Doctor: If your baby’s condition worsens or home remedies aren’t working, consult your pediatrician for further evaluation and treatment options.
Things You Need to Know
Caring for a newborn can be overwhelming, but here are some tips to make it easier:
- Spit-Up Rags: Always have a burp cloth or spit-up rag nearby. Newborns often spit up after feeding, and it can be unpredictable.
- Burping: When burping your baby, try rubbing their back in a circular motion rather than tapping. This can be more soothing and just as effective.
- Head Support: Always support your baby’s head and neck when holding them, as they haven’t developed strong neck muscles yet.
- Layering for Temperature: Dress your baby in layers if cold outside to help regulate their temperature. Avoid bulky clothing like coats when in a car seat, as it can interfere with the straps’ safety.
- Sun Protection: If it’s hot outside, make sure the baby wears a hat AND sunscreen. Babies can easily overheat and die without proper sun protection.
- Screen Time: Decide early on how you’ll handle screen time. Babies don’t need screen time, and avoiding it can promote healthy cognitive development. Most pediatricians ask that you avoid it until at least the age of two, but as a modern day parent who needs to work and or get things done around the house, this may not be feasible. Don’t feel guilty if you do end up relying on a bit of dancing fruits for some ‘me’ time; like most other things, everything in moderation.
- Strengthen Boundaries: Your baby will let you know when they are noticeably uncomfortable, especially if they’re reading your body. If you do not feel comfortable with someone handling your baby or the baby is visibly upset, please do everything you can to remove yourself and your child from the situation as quickly as possible. This means taking the baby from them, or giving an excuse as to why they are unable to hold them at this time. For years you have been your own advocate, and what you used to tolerate will have to be reevaluated. Now that you must put your child’s needs first, including their comfort and safety, you will need to create stronger boundaries.
The Baby Stage – You Either Love it or Hate it.
The 0-3 month period is full of growth and learning for both you and your baby. As you navigate these early stages of parenthood, remember to cherish the small moments and trust in the process—your baby is developing rapidly, and with each day, you’ll learn more about their unique personality and needs.
