We are going to a birthday party for a boy in DD's daycare. He is turning 2. I would like to spend between $10 and $15. He is interested in pretty normal 2 year old stuff. Cars, trucks, things with buttons/sounds, water toys, and books. He is into Toy Story, Kung Fu Panda and Cars. Any suggestions on what to buy? I don't know anything about 2 year olds and very little about what boys like since I am used to a 1 year old girl.
