Week 3

Your baby is 3 weeks old

Baby says this week

Though my movements are still random and jerky, I can start snuggling by week three. As you hold me, watch how I adjust my posture towards you. I will find your arms and even your scent calming and comforting.

Your Baby's Development

2 min read

Your baby is putting on weight fast this week. Movements are becoming smoother and less jerky, and tummy time (always supervised) will help with head control. Eyes are sharper too, you'll notice your baby tracking patterns and faces.

But yes, the crying. Around 1 in 5 babies go through long, hard-to-soothe crying in these early weeks. If it lasts more than 3 hours at a stretch, at least 3 days a week, doctors call it colic. The good news is, it always passes, usually by month 3 or 4.

Things that sometimes help
  • Hold baby upright after feeds. Try a warm bath. Gentle tummy massage (clockwise). White noise. Rocking. A drive. Skin-to-skin contact. Nothing works for every baby, try what calms yours.
The most important thing to know
  • If you feel yourself getting overwhelmed by the crying, put your baby down in the crib (safely, on the back, firm mattress) and walk into the next room for 10 minutes. Call your partner, your mother, a friend. Never shake your baby, even a few seconds of shaking can cause serious brain injury. Crying won't harm a baby. Shaking can.
Safe sleep reminder
  • Back to sleep, firm flat mattress, nothing soft in the crib. This stays the rule until your baby is 1 year old.
Indian-home sleep cue
  • Many Indian families share a room, and that is fine for the first 6 months, in fact protective against SIDS. Keep your baby on their own firm flat surface (not in your bed), and a soft lori (lullaby) works the same magic in any home.

Even the crying seasons are chapters, not the whole book. Through every hard evening, your steady presence is doing invisible work; comfort is baby development too, and you are giving it in generous measure.

Three weeks in. Sleep deprivation is doing its thing. The smallest decisions feel hard. This is not a sign you are doing it wrong, it is a sign you are doing it.

Sleep when baby sleeps, really

  • You have heard it a hundred times. Treat it like a prescription, not a suggestion. Even a 20-minute nap when baby naps stacks up. Tell-tale signs you need to stop and lie down: brain fog, irritability you do not recognise, dropping things, missing words mid-sentence.

Eating for recovery and milk supply

You need around 450–500 extra calories a day if you are exclusively breastfeeding. Indian foods that fit:

  • Methi paratha or methi-bajra rotis (iron + galactagogue)
  • Gond ke laddu, panjeeri, sonth laddu (warming, calorie-dense)
  • Dal-rice with a spoon of ghee (protein + fat)
  • Curd, paneer, milk (calcium + B12)
  • A handful of soaked almonds and 2 dates a day

Drink water with every feed. Coconut water and jeera water are good additions.

Watch for the "still bleeding heavily" red flag

  • By 3 weeks, lochia should be lightening to pink or brown. If you are still soaking pads, or bleeding bright red, or passing big clots, call your gynae. Late postpartum hemorrhage is real.

Mental health is health

  • If sadness, dread, or scary thoughts keep getting louder, you may be dealing with postpartum depression, affecting around 1 in 5 Indian mums. It is not a personal failure; it is a treatable medical condition. Talk to your gynae, a trusted GP or a therapist.

Tradition with a small caveat

  • Most Indian postpartum food traditions, warm khichdi with ghee, methi laddu, ajwain water, sonth laddu, are genuinely supportive. A few older customs (no cold water for 6 months, no bathing for weeks, total dietary restriction) are not medically backed. Take what feels right and gently set aside what does not.

Warm khichdi, soft laddus, water beside you at every feed: the food traditions around you exist to hold you up. A nourishing diet after delivery is your family's way of loving you back; accept every warm plate without keeping score.

Your Care Essentials

New Born Tape Diapers | Up to 5Kgs | 9 Count

Your newborn is going through 8 to 10 nappies a day, and you're working out which brand keeps the cot dry through the night. Newborn skin is paper-thin, so a soft cotton-feel sheet, snug fit around the umbilical stump, and a wetness indicator earn their keep. Try Mylo Newborn Tape Diapers that:

  • 12-Hour Absorbency, Dry Nights.
  • Cotton-Soft On Newborn Skin.
  • Cord-Cut Fit + Wetness Strip.

Nappy after nappy, you are keeping a rhythm nobody warned you about, and keeping it beautifully. Somewhere between the changes and the cuddles, remember that the hands doing all this deserve rest too; share the night shifts where you can.

Stretch Marks Cream - 100 gm - Pack of 2

By week 3, the belly is softer and pregnancy stretch marks are now in full view: pinkish, slightly raised lines on the belly, hips and thighs. Daily moisturising with cocoa butter and shea makes the biggest difference now, while the skin is still bouncing back. Safe to use while nursing. Pregnancy-safe Indian skincare habit: soft, faint, daily. Try Mylo Stretch Marks Cream that:

  • Cocoa + Shea Cream.
  • Lightens Old & New Stretch Marks.
  • Non-Greasy, Quick Absorb.

Those lines arrived while your body was busy making a person; they deserve patience, not judgment. Let the daily minute of cream be a small truce with the mirror, a habit of gentleness in a season that asks so much of you.

Your Baby's Vision

Faces are still a blur. Your baby sees your hairline and eyes as light patches, not features yet. Hold them close and they'll still soften at your voice. Look at the comparison below.
Try This : Lean in real close during a feed. Even blurry, your face is already their favourite shape in the world.

Visitor Fatigue

Tip

FAQs Related to Week 3 of Baby

A 1 month old baby should feed every 2 to 3 hours, or whenever they show hunger cues. On-demand feeding is best at this age, for both breastfed and formula fed babies. Trust your baby: they know how much they need, and frequent feeds are a healthy sign.
A healthy weight for a 1 month old baby is best judged by steady gain along their own growth curve, not by any single number. Frequent feeds and plenty of wet nappies tell you things are going well. Your pediatrician will plot growth at every checkup and reassure you.
By week 3, a 1 month old baby is gaining weight steadily, moving more smoothly, and starting to track faces and high-contrast patterns with sharper eyes. Supervised tummy time is quietly building head control. Some long crying spells are normal too. Remember, every baby develops at their own pace.
You can start gentle walking and easy breathing exercises within days of a normal delivery, but wait for your doctor's clearance, usually at the 6 week checkup, before anything more strenuous. Your body is still healing, so go slow and be kind to yourself.
