Child Development: 4 - 8 Months

Babies from 4-8 months may explore objects with their mouth and by kicking, reaching, grasping, pulling, and letting go. They love discovering new skills. Babies at this age can smile, laugh, coo, and reach out to interact with their parents and other caregivers. They love to listen and respond to language by copying the sounds and rhythms of what they hear.

Take a look at the categories below to see different ways you can help your child develop.
