Your baby at 3 months

A daily rhythm is quietly appearing. She's found her hands, maybe her voice's volume knob, and the newborn fog is lifting for both of you.

Every baby has her own rhythm. These are gentle, typical ranges — here to reassure you and help you feel calm and confident, not rules to measure her against. Trust what you see. If something is ever on your mind, your pediatrician or well-baby nurse is always there for you.

Development this month

Milestones show up across four areas — and they arrive in any order, at her own pace.

What you might notice

Sleep around this age

Sleep is the question new parents ask most — so here's the typical shape of it, gently. Some days won't match, and that's normal.

Every baby's clock is her own. Shift the whole day earlier or later to fit hers — the wake windows matter more than the exact times.

Ranges based on AAP, Polly Moore, and pediatric well-baby guidance. In the app, BabyBloomy predicts her next window from her own pattern — and never pings you between 10pm and 7am.

Feeding

Breast milk or formula, on demand. There's no schedule to hit — frequent, cluster, and night feeds are all normal. Expect 8–12 feeds a day early on.

Play & connection

Play is how she learns — and the easiest logging you'll do. A few ideas for right now:

Health & safety: Always place her on her back to sleep in a bare crib, never leave her on a raised surface, and keep her car seat rear-facing. For anything that worries you, your pediatrician or well-baby nurse is the right call — never a forum.

Moments worth keeping this month

The first years disappear fast. A two-tap log now becomes a page later.

You might be wondering

Should she be on a schedule?

A gentle rhythm — feed, play, sleep — helps more than fixed clock times at this age. Wake windows around 90–120 minutes are typical.

Is drooling a tooth?

Lots of drool now is usually just active salivary glands, not always teething. First teeth often arrive later.
