These types of toys spark babies’ imaginations and help them build and practice new skills. Some push toys, such as doll strollers and lawnmowers, inspire pretend play too. Others add a lesson in cause and effect (say, if that lawnmower produces soap bubbles as your baby pushes it, or a puppy opens and closes its mouth as it rolls). There are all sorts of building blocks to share with your baby: Traditional wooden blocks, blocks that snap together, plastic blocks and blocks that make music. Look for blocks that are durable, easy to clean, non-toxic (they will be going in your baby’s mouth!) and right-sized for little hands. Small toy cars and trains also require grasping skills that strengthen your baby’s hands; just make sure they are designed for young babies and toddlers and are not choking hazards. He might like a toy phone (there are some non-electronic versions), a baby-sized vacuum cleaner, or a little backpack to carry his things.
