If ever??

We actually have hardly any toys for DS. Has its ups and downs. All his toys are stuffed, rattles, infant toys, and he has very few. We had a play date today and he LOVED all the toys at their house - I had no idea he would love toys so much. It was so cute. But it's making me consider buying him a few new things.

What types of toys do you buy your baby? Do you have an favorites for 6mos+?
