Welcome to one of the most quietly remarkable stretches of your baby's life. In these first three months your newborn moves from sleepy, reflexive bundle to a tiny person who locks eyes with you, follows a moving toy and breaks into a gummy, whole-body smile. And if you find yourself comparing notes with the mothers' group, rest easy — there is a wide, normal range, and most of what you'll see unfolds gently and in its own time.

What you might notice (and roughly when)

Every baby is different, and these are typical windows rather than firm dates.

Typical 0–3 month milestones

  • Tracking with eyesFollows your face or a high-contrast toy side to side, often by 6–8 weeks.
  • Social smileA true smile in response to you, usually around 6–8 weeks.
  • Head controlLifts head briefly during tummy time; steadier by 3–4 months.
  • CooingSoft vowel sounds (ooh, aah) and back-and-forth 'chats', often from 6–10 weeks.

Ranges vary — and that's normal

Milestones are best thought of as a spread across many weeks, not a single deadline. Two healthy babies can reach the same skill a month apart.

A few things genuinely shift the timeline:

  • Prematurity. If your baby was born early, use their corrected age (age from the due date, not the birth date) for milestones, often up to around 2 years.
  • Temperament and opportunity. Calm, alert moments and plenty of face time and floor time give babies room to practise.
  • Individual pace. Some babies smile early and find head control later, or the reverse.

Guidance is consistent here across the Raising Children Network (AU), the AAP (US) and the WHO — watch the overall pattern of progress over time rather than any single date.

Gentle ways to help

You don't need flashcards or special toys. Your face and voice are the best learning tools your baby has.

  • Tummy time while awake and supervised, a few minutes at a time, builds neck and shoulder strength for head control.
  • Get face to face about 20–30 cm away — that's roughly where newborns focus best — and let them study you.
  • Talk, sing and pause. When your baby coos, coo back and wait. These tiny "conversations" build language.
  • Offer high-contrast patterns or slowly moving objects to encourage tracking.

What to mention to your nurse or GP

Your child-health nurse (AU) or paediatrician (US) checks development at routine visits, and you don't need to wait for an appointment if you're worried. By around the 3-month mark, it's worth raising it if your baby:

  • Isn't smiling responsively at people
  • Doesn't follow movement with their eyes, or eyes seem to cross most of the time
  • Isn't starting to lift their head during tummy time
  • Isn't making any sounds, or seems unusually stiff or floppy
  • Doesn't react to loud sounds, or you have any concern about hearing or vision

Trust your instincts — you know your baby. Raising something early is always reasonable, never a bother.

A quick word on the rest of the picture

Development doesn't happen in isolation. Steady feeding, plenty of contact and the slow settling of sleep all support those new skills.

If anything here raises a question about your baby's health, growth or development, your GP or child-health nurse is the right person to talk to. This guide is general information to reassure and orient you — not a diagnosis.

You're doing the most important work already: showing up, holding, talking and noticing. That's exactly what these three months ask of you.
