Cub likes to jump off of things - the couch, the side of the pool, the dog - that's not really new. What's new is his counting before jumping.
He's not really consistent - sometimes he counts to three (which kind of makes sense), but other times he counts to eight or seven and then jumps so Buttin and I aren't always prepared to catch him or cheer. I'm going to tell his aunt Liz that he's doing complex physics equations before jumping.
Here he is counting before throwing the basketball at me.
