Tyler's Swimming Lessons

We started Tyler on his first round of swim lessons. He is doing so well with it. I feel like he is fairly safe at the pool as long as he has his floatie on, but I really worry about him jumping into deep water without it, thinking that he has it on. He gets along really well with his teacher, Peter. There are just three little boys in the class.

I tried to put a short video of him floating on his back all on his own, but I'm not sure it is going to work.
