Infant developmental milestones by week

Infant developmental milestones by week outline the rapid changes babies experience in their first months of life. While every child develops at their own pace, weekly milestones provide a helpful guide for parents:
  • Week 1–2: Strong reflexes (grasp, rooting, startle), responding to sound, brief eye contact.
  • Week 3–4: More alertness, beginning to focus on faces, slight head movements during tummy time.
  • Week 5–6: Social smiling starts, more controlled arm and leg movements.
  • Week 7–8: Improved head control, cooing sounds, responding to familiar voices.
  • Week 9–10: Following objects with eyes, recognising caregivers’ voices more clearly.
  • Week 11–12: Increased babbling, stronger grip, beginning to push up on arms while on tummy.
These weekly guides help parents see progress in motor skills, communication, and bonding. If milestones are delayed, it doesn’t always mean something is wrong — but early support and assessment can make a big difference.
