Newborn · Week 3 · Newborn
Your 3-Week-Old Baby
The early days are about feeding, bonding and rest. Your baby is adjusting to life outside the womb, and so are you.
Milestones describe common patterns, not deadlines. Every baby develops at their own pace.
Week 3 of 52
49 weeks until the first birthday
This shows time in the first year, not how your baby is developing.
This week at a glance
Movement
Reflexes and lots of sleep; brief alert moments.
Communication
Calms to familiar voices; cries to communicate.
Feeding
Frequent responsive milk feeds, day and night.
Sleep
Short stretches around the clock; day–night still mixing.
These are common patterns for this stage, not requirements for this exact week.

Note what you have noticed so far. “Not yet” is completely normal.
Development and milestones
Movement
- Reflexes like rooting and grasp
- Turns head to the side
- Jerky, unco-ordinated movements
Thinking and understanding
- Focuses briefly on faces up close
- Prefers high-contrast patterns
Communication
- Cries to signal needs
- Calms to a familiar voice
Social and emotional development
- Settles with skin-to-skin
- Gazes at faces during quiet-alert moments
Newborn skills emerge across a wide range. Quiet or sleepy days are completely typical at this stage.
Feeding
Breast milk or infant formula provides all the nutrition your baby needs at this stage. Feed responsively — follow hunger and fullness cues rather than a fixed schedule.
- Feed on demand — breast, formula or a combination
- Watch hunger cues and count wet nappies
- Burp partway and after feeds if it helps
- Prepare formula safely, following the tin's instructions
- Solids are usually not needed before around 6 months
- No honey before 12 months
Feeding safety
- Hold your baby semi-upright for feeds
- Never prop a bottle
- Prepare and store formula safely
- Wind gently and watch for comfortable settling
Sleep
Common sleep pattern
Newborns sleep in short stretches around the clock — often 14–17 hours total, but rarely in long blocks.
Why sleep may change
- Day–night rhythm still settling
- Frequent feeds
- Growth spurts
- Needing help to settle
What may help
- A calm, dim environment for night feeds
- A gentle wind-down
- Watching short awake windows
- Skin-to-skin and gentle motion
Safe sleep reminder
- Place your baby on their back to begin sleep
- Use a firm, flat sleep surface
- Keep pillows, bumpers, toys and loose bedding out of the cot
Play and activities
Face-to-face time
Supports: Bonding and focus
Hold your baby about 20–30cm away and talk softly.
Safety: Support the head and neck.
Tummy time
Supports: Neck and shoulder strength
A minute or two on the tummy while awake and watched.
Safety: Always supervise; stop if upset.
Gentle sounds
Supports: Listening
Sing or hum during calm moments.
Safety: Keep sounds soft.
Skin-to-skin
Supports: Calm and regulation
Hold your baby against your chest.
Safety: Keep the airway clear.
Babyproof before the next step
Mobility safety matters a lot at this stage. A quick sweep now keeps new skills safe.
- Follow safe-sleep basics every sleep
- Support your baby's head and neck
- Keep a smoke-free environment
- Use a rear-facing car seat correctly
- Never shake a baby
Growth
Growth is a pattern, not a weekly target.
What matters most
- Weight, length and head circumference tracked over time
- Whether your baby keeps following their own growth pattern
- Feeding, energy and overall wellbeing
- Any sudden change in the growth curve
Percentiles are read alongside the overall pattern — not used to diagnose on their own.
Vaccinations to check
There is no universal vaccine assigned solely to Week 3. What is due depends on several things, so check your baby's record rather than assuming a schedule.
What is due depends on:
- Previous doses already given
- The Universal Immunization Programme (UIP) schedule
- The Indian Academy of Pediatrics (IAP) schedule
- Your state programme
- Your paediatrician's guidance
- Any catch-up requirements
If you are signed in with a baby profile, your next recorded vaccine appears on your dashboard. Always confirm timing with your paediatrician.
When to contact a doctor
Seek urgent medical care
- Breathing difficulty or blue lips/face
- A fever in a young baby that worries you
- Baby is very difficult to wake or unusually floppy
- Persistent vomiting or refusing feeds
- Signs of severe dehydration
- A seizure or loss of consciousness
Discuss promptly with your paediatrician
- Not making eye contact or not turning to sounds
- Not feeding well or poor weight gain
- Very stiff or very floppy muscle tone
- Loss of a previously acquired skill
Loss of a previously acquired skill should be discussed promptly.

Frequently asked questions
How often should a newborn feed?
Most newborns feed frequently, often 8–12 times in 24 hours, responsively. Follow hunger cues and wet nappies rather than the clock, and speak to your midwife or doctor if you are worried about feeding or weight.
Is it normal for a newborn to sleep most of the day?
Yes — newborns often sleep 14–17 hours in short stretches. Wake for feeds as advised, always place your baby on their back to sleep, and contact your doctor if your baby is very hard to wake or feeding poorly.
Why does my newborn startle so much?
The startle (Moro) reflex is normal and fades over the coming weeks. Swaddling for sleep can help some babies settle, following safe-sleep guidance.
How many wet nappies should I expect?
Several wet nappies a day is a reassuring sign your baby is getting enough milk. Watch feeding, mood and nappies together, and speak to your doctor if wet nappies drop off or you're worried about intake.
Could my baby be teething?
Teething can start any time in the first year — drooling and gnawing are common. Offer a clean, safe teether; see your doctor for a high fever, which teething itself does not cause.
When is the next vaccination?
Vaccination timing depends on your baby's record and the schedule your paediatrician follows. Check the immunisation card and confirm the next date with your clinic.
