By 4 months your baby may

  • grab at a toy if it is held close.
  • smile at everyone, coo, laugh, especially for their parents.
  • squeal happily.
  • hold their head steadily when pulled into sitting position.

You can encourage development by:

  • propping them up to see what is going on.
  • sitting him in a bouncinette (not on a table or high surface).
  • giving them tummy time on the floor.
  • placing a plastic mirror in front of them.
  • talking to them while you are feeding and changing them.
