By the time your baby is four months old he or she has already developed their own personality. They know when you call their name and can be soothed by the sound of your voice. Over the next few months you’ll see your baby becoming more curious of their surroundings and starting to play and communicate with other babies and toddlers.

The following information has been sourced from the Early Years Learning Framework Developmental Milestones booklet, developed by Community Child Care Co-operative Ltd NSW (CCCC) for the Department of Education. 

How can you encourage your baby’s learning?

  • Mimic their sounds and actions e.g. clapping, waving
  • Encourage their motor skills e.g. place a toy out of reach and urge them to crawl towards it
  • Play games e.g. peek-a-boo, splash time in the bath, go to the mirror and show their reflection
  • Play together on the floor to encourage your baby to stretch, wriggle and roll
  • Tickle and laugh with your baby
  • Read them books with simple, bright pictures
