On Monday, when she got in the pool she seemed to forget whatever she learned last year. But as the week went on, she got better at everything. By today, she was able to float on her back on her own for an extended time, swim about halfway across the pool (kicking, paddling, and blowing bubbles all at the same time!), and jumping into the pool! She's still not quite where I'd like to see her at, but it's better than she was doing last year. She's still going to have a group lesson once a week until the end of July.
The one odd thing was that my daughter would get nervous when the instructor had her swim to her. Even today, she would appear to freeze up when asked to swim. I noticed the reason appeared to be that she got overwhelmed. I saw her thinking about the paddling, kicking, and blowing bubbles as she stood by the wall of the pool. It looked like her brain was about to short-circuit thinking about it all. But she would finally kick off the wall and do everything she was supposed to do. I guess with practice this will come second nature and won't take all that brain power. I hope.
