what would be an appropriate and exciting gift for ds when I have a baby? he is going to be 2 1/2 yo. he likes pretty much all boy's toys, but I want something inexpensive. dd will be getting another doll (a girl can never have enough dolls), but I dont know what to get for ds. last time I had a baby, I got him a coloring book and crayons (his first of both being that he was only 16 mo) which didnt really interest him too much. any good ideas??
