This is one tidbit of an example of how much Brock loves to climb. He climbs out of the pool. He climbs the stairs at least 6 times daily. He even made it on top of the coffee table/ottoman - no idea how he accomplished that one, there is absolutely nothing to grip. And he attempts to climb just about everything else.
It's just a good thing that once he makes it to the top, he does not attempt to come back down on his own, on the stairs anyway (don't ask how we know this...)
