My 17 month old twin boys are the same way... we have a small slide in our house that they love to climb and slide down again and again. Also we have small inflatable pool filled with ball pit balls that they love to play in. I have found that just keeping a handful of toys out and every other day rotating to hte bunch really helps keep their attention because the toys are always new! I am not looking forward to a long MN winter I think they might climb the grandfather clock by winters end..

Blessings and have fun chasing your guy around.
