My 18 month old is a typical active boy, but I'm struggling with how to help him burn off energy inside now that the weather is colder.

He likes to run behind his push walker and rolling cars around, but he can get a little rough with it. He also climbs to furniture, which is still not safe. We don't have a very big house, so he tends to bop around from room to room and leave a mess.

Any toy suggestions? Ride-ons, play tent, etc?
