we got him a shopping cart since he loves to push stuff around (with or without wheels). he also likes to collect stuff. we made the mistake of presenting it with dotty inside of it. but she got scared when nj was pushing the cart and jumped out. so he took the lion and threw it out of the basket. i asked him to pick up the lion, but he tried to pick up dotty instead! of coarse, she was scared and ran away. now all he wants is dot dot back in the cart.
