While some babies at this age are crawling and some are walking, they all have something in common—they are active! Toddlers are keen to explore their environment and to interact more with other people. They seek every opportunity to play, which is important, because they learn about appropriate social interaction through playing with other children and adults. Toys now begin to play a bigger part in your child’s life. Researchers suggest that toys that are responsive to your child’s actions are helpful at this age.
