Yes! It's a cast!

Micah fell in the backyard a week ago. He has a small fracture in his right wrist. So far he's doing fine with it, but it is so nasty and dirty. I'm not sure I can take three weeks of the smell. How do you tell a toddler to keep his cast clean? Some of you may remember, but Coley broke her arm at about the same age. I'll post a picture of that!
