Baby Milestones: The Complete Week-by-Week Guide for New Dads

Your baby's first year is a whirlwind of changes, and knowing what to expect can make all the difference between panic and confidence.

During weeks 1–4, your baby is adjusting to life outside the womb. They'll mostly sleep, eat, and cry — and that's completely normal. You might notice them startling at loud noises (the Moro reflex) and gripping your finger tightly. These are primitive reflexes that disappear over time.

By weeks 5–8, something magical happens: your baby starts to focus on faces. They'll begin tracking objects with their eyes and might reward you with their first real smile. This is the moment that makes those sleepless nights feel worth it.

Weeks 9–12 bring more interaction. Your baby will start cooing and making vowel sounds. They'll discover their hands and spend ages staring at them. Tummy time becomes increasingly important for building neck and shoulder strength.

From months 3–6, the pace picks up. Rolling over, reaching for toys, laughing out loud — every week brings something new. Your baby might start showing interest in solid foods around the 4–6 month mark, though breast milk or formula remains their primary nutrition.

The second half of the year is where things get really exciting. Sitting up independently, crawling, pulling to stand, and maybe even those first wobbly steps. Every baby develops at their own pace, so try not to compare — your kiddo will get there.

Remember: milestone charts are guides, not deadlines. If you have concerns about your baby's development, talk to your pediatrician. They've seen it all and can offer reassurance or early intervention if needed.
