We went to the pool late Saturday afternoon and stayed for about an hour which was plenty of time to exhaust him. Thankfully it wasn't too crowded and most of the people were playing pool volleyball at one end of the pool so we just hung out on the opposite end. The pool manager was very sweet and accommodating to Noah. The music was blaring when we got there and that's a little too much for him in an already noisy setting so I explained that it agitated him and asked if she could turn it down a little bit and she was super nice about it. She even came over to warn Noah that the lifeguards were going to be blowing their whistles soon so that it wouldn't startle him.
He seemed most comfortable floating on his back but would do some kicking and what not while floating. I think it was good exercise for him and he clearly enjoyed it. I'm sure we'll be going back again soon.
