Moving toys
Your baby is learning to roll, walk and crawl in these critical months. She is also becoming interested in toys that move.

Activity toys
Activity toys allow little fingers to explore the world.The best activity toys have several actions, for example parts that can be opened, moving parts, safe mirrors, handles to pull and things to chew. These toys provide sensory entertainment and teach cause and effect as your baby operates the parts. Lamaze offers several great soft activity toys for the six to nine month age range. Look for their “Spike the Dinosaur” or “Multisensory Clutch Cube”．
Books
Board books or books printed on cloth are perfect for babies of this age.
