My almost 5 yr old is extremely hyper......I have given up trying to calm him down. We spend a lot of time walking, bike riding, parks, soccer, jumping on the trampoline etc. I think I have exhausted him and an hour later he is literally bouncy off the walls again. My desperate question is, what can I do with him in the house? When I am tired or his sister is sleeping or the weather is crappy I need him to blow off steam indoors. I want to know if anyone has some good toys, games, or activities that can help my ds use up his energy. TIA!
