The First Four Weeks with Your Newborn:
What to Expect, Common Concerns, and When to Call the Pediatrician

Bringing home a newborn is an exciting and emotional experience. The first four weeks can be both magical and overwhelming as you adjust to life with your little one. As a new mom, you may have many questions and concerns about feeding, sleep, diaper changes, and your baby’s overall well-being. Here’s what you can expect, common concerns, how to manage them, when to call your pediatrician, and when to schedule your baby’s well visits.
Newborn Well Visits: When to See Your Pediatrician
Regular well visits are essential for tracking your baby’s growth and development, addressing feeding concerns, and ensuring they are healthy. Here’s when you should schedule well visits in the first month:
- First Visit: 3-5 Days After Birth
- Your pediatrician will check your baby’s weight, feeding habits, and jaundice levels.
- Second Visit: Around 2 Weeks Old
- This visit ensures your baby is gaining weight properly, feeding well, and adjusting to life outside the womb.
- One-Month Checkup
- The pediatrician will monitor developmental milestones, head control, and address any sleep, feeding, or digestive concerns.
These visits are a great time to ask questions and discuss any worries you have! If your baby was born prematurely or had complications at birth, your pediatrician may recommend additional visits.
Week 1: Adjusting to Life with Your Newborn
Your baby is finally here, and you’re adjusting to round-the-clock care. In the first few days, your newborn will:
- Sleep: Newborns typically sleep about 16 to 17 hours a day, often in short stretches.
- Feeding: Newborns usually feed every 2-3 hours. It’s common for babies—especially breastfed ones—to lose up to 10% of their birth weight in the first few days of life. However, by the end of the first two weeks, they should have regained this weight and continue to gain about 1 ounce per day.
- Diaper Changes: Expect several wet and soiled diapers daily. By the end of the first week, your baby should have at least six wet diapers per day.
Common Concerns & How to Manage Them
- Latching and Feeding Difficulties: Breastfeeding can take time to master. If you experience pain, poor latch, or low milk supply, reach out to a lactation consultant or your pediatrician.
- Jaundice (Yellowing of the Skin and Eyes): Mild jaundice is common. Ensure your baby is feeding well and having plenty of wet/dirty diapers. If jaundice worsens or your baby seems overly sleepy, call your pediatrician.
- Umbilical Cord Care: Keep the stump dry and let it fall off naturally. Contact your doctor if there’s redness, foul odor, or discharge.
When to Call the Pediatrician:
- Baby isn’t feeding well or has fewer than six wet diapers per day by the end of the first week.
- Persistent yellowing of the skin or worsening jaundice.
- Fever of 100.4°F (38°C) or higher.
Week 2: Sleep Deprivation & Finding a Routine
By the second week, you may be feeling the effects of sleepless nights. Your baby is still adjusting to life outside the womb, and you’re learning their cues and needs.
Common Concerns & How to Manage Them
- Baby Sleeps All Day and Is Awake All Night: Help your baby learn the difference between day and night by keeping daytime feeds and interactions stimulating while keeping nighttime feeds quiet and low-light.
- Cluster Feeding: It’s normal for babies to want to nurse frequently during growth spurts. Follow their cues and ensure you’re staying hydrated and nourished.
- Gas & Fussiness: Some newborns struggle with gas. Help them by burping frequently, keeping them upright after feeds, and using tummy time to relieve discomfort.
When to Call the Pediatrician:
- Baby is excessively fussy and inconsolable for long periods.
- Signs of dehydration (sunken soft spot, dry mouth, few wet diapers).
- Persistent vomiting, not just spitting up.
Week 3: Baby’s First Smiles & Developmental Changes
At this stage, your baby is becoming more alert and responsive. They may start making eye contact and even give you their first tiny smile!
Common Concerns & How to Manage Them
- Baby wants to be held all the time: This is completely normal! Newborns feel safest when close to their parents. Baby-wearing can help keep them close while giving you some hands-free time.
- Spitting up after feedings: A small amount of spit-up is normal. Keep your baby upright after feeds and burp frequently. If they’re projectile vomiting or seem in pain, consult your pediatrician.
- Baby acne: Small red pimples on your baby’s face are normal and will go away on their own. Avoid harsh soaps and lotions.
When to Call the Pediatrician:
- Signs of reflux (constant spit-up, choking, back-arching during feeds)
- Sudden decrease in appetite or extreme lethargy
- Signs of an infection (redness around the umbilical cord stump, eye discharge)
Week 4: Gaining Strength & New Milestones
By now, your baby is growing stronger and starting to lift their head during tummy time. They may also be more awake during the day and recognizing your voice and face.
Common Concerns & How to Manage Them
- Sleep is still unpredictable: It’s normal for newborns to have irregular sleep patterns. Try to create a bedtime routine, but don’t stress about a strict schedule yet.
- Baby seems congested: Many newborns have nasal congestion. Use a saline spray and a bulb syringe to clear their nose if needed.
- Cradle cap (flaky scalp): This harmless condition can be treated by gently massaging the scalp with baby oil and brushing with a soft brush.
When to Call the Pediatrician:
- Persistent congestion affecting breathing or feeding
- High fever (100.4°F or higher)
- Signs of difficulty breathing (flaring nostrils, grunting, fast breathing)
Remember: Trust Your Instincts
The first four weeks can be a whirlwind of emotions, but remember—you’re doing great! Every baby is different, and it’s okay to ask for help when needed. Trust your instincts, and never hesitate to call your pediatrician if you have concerns.
Regular well visits are essential to ensure your baby is growing and developing properly. Make sure to schedule and attend your baby’s 3-5 day, 2-week, and 1-month checkups to stay on top of their health.
Your baby is growing and changing rapidly, and before you know it, they’ll be out of the newborn phase. Enjoy the snuggles, take care of yourself, and embrace this special time with your little one.
