We have friends who have some property up on one of the lakes up north (I can't remember which one) and they invited a bunch of people out to play in the water. It was a beautiful day and both kids were pretty well behaved.
This is what Ayden spent a lot of time doing. It's what he does most of the time at any beach we go to.
When he wasn't playing in the sand, he was sitting in the canoe.
Abby didn't swim, but she usually doesn't and is mostly content not to.
And when Ayden wasn't in the canoe, he was riding in the boat, which he LOVED. Rachelle even let him drive.
