Waterless swimming

This weekend, Tyler and I tried to do some yard work, so I took Griffin outside with us and placed him in his swimming pool with some toys to play while we worked. I thought he might try to get out of it so he could crawl around, but he didn't. He sat right there and played like a good boy. He enjoys being outside in the sunshine. So Griffin has swam waterless.
I am eager to fill his pool up with water soon and hope it will be nice enough at his birthday party to have out for the kids to swim.
