Henry is FEARLESS! He just started running to get on this. He just doesn't have long enough legs to boost himself up on to things. The first slide (a quite tall one!) he went down by himself, but after that I made him go down with me so he wasn't waiting for me on either end. He had so much fun and ended up taking a 3 hour nap today, normally it's a 2 hour nap. He moved non-stop and only stopped for 10 minutes when we had snack. This was at the Burnsville Pump It Up!
