A phase of active games
Hyperactive behavior is normal among kids, and I’d recommend you to let your kids express this energy. Don’t you think it’s great when your sons are playing with each other? I have a daughter and a son, and both of them are pretty calm as long as they don’t see the wooden playground. They can play there for several hours, and I think you can buy something like that for your sons so they can express their energy. Our playground is from goodevas, but I think it’s easy to find something similar.
