Your Baby At 3 Months

All babies develop at different rates and it’s no different for 3-month-old babies. Don’t fret if your baby misses a development milestone – he or she might be some weeks ahead on some milestone and a bit behind on others but it will even out eventually.

If you’re concerned that your baby has missed key milestones altogether, speak with your doctor. This guide shows what to expect from your three-month-old baby.


Each baby has his or her own sleep needs. That said, your 3-month-old needs 16 hours of sleep each day, with about three to four hours of daytime naps. At this age, your baby will now be managing about 5 hours of sleep. But if your baby doesn’t follow this routine, don’t worry – it’s common for many babies since they need the energy from consistent feeding to sustain their growth.


At this age, your baby needs breast milk. Your 3-month-old baby may have a growth spurt at this age. So they’ll be hungrier than usual. Furthermore, your baby will drink about 720ml to 1200ml daily spread over 5 to 8 feeds.

Movement and head control

Babies are more robust during this age! When you keep your baby’s shoulders in a sitting position, they can look steadily while maintaining a straight back. During tummy time, your baby can lift his or her shoulders and head off the floor for some moments.

Sight and hearing

At this age, your child’s sight has developed – meaning he or she is alert visually, particularly looking at faces and people nearby. He or she can focus on a swinging toy about 20cm in front of them and will give at it from side to side. Your baby’s hearing will also improve and will show that he or she is happy when he or she detects footsteps and voices close by.


At three months old, your baby will charm you and other family members with many smiles, eye contact, hand gestures, and happy baby ‘talk’ when he or she is happy. Your baby might even reward you with his first chuckle! But no doubt, your baby will let you know when he is uncomfortable, annoyed or hungry by crying.

How to help your baby develop

  • Baby activity centers or gym are perfect for training hand-to-eye coordination
  • Promote baby giggles by tickling them gently. You can also try games like peek-a-boo and other fun games
  • Include talking as part of your baby’s daily routine, read to them and let them feel objects with different textures

If you’re concerned or have any questions about your child’s development, speak with your baby’s pediatrician for help.
