Swimming and school

We've been swimming a ton this summer. At the beginning of the summer, Levi would stay on the top step, having fun but still afraid to put his face/head in the water. After no lessons and no parental pushing, here's what he's doing now:

We are less than one week away from the start of school! Nate and Lucy start on September 5. I'm planning on doing a small "night before first day of school party" for dinner on Tuesday, with their favorite foods, dessert, decorations, etc.--something to make it special but not too involved (so I don't have to live up to anything too huge next year!). Both Nate and Lucy are excited but nervous to start school. Nate has been saying he doesn't want to go, but I know the reason for that is he wants to keep playing video games for hours a day. I know he's going to love school and hope it's a smooth transition.
