This post is just for the record of it... but Brock was helping me clean the pool this morning and fell in.
He did great... he was able to swim enough (not really above water), that I could reach him from the side. And when I pulled him out, he was most upset that he got his pajamas wet.
We talked about what happened, and how we always need to be safe around the pool.
He was swimming an hour later, clearly not even phased by it. (I was hoping for a little phasing, so that maybe he might learn from it.... we'll see).
