One Size Fits All?

Maybe this picture is inappropriate. I apologize if it is. But there's a story with it:
Nils took these shorts off one of their teddy bears. The were originally preemie pants. Honestly. They still have the tag on them. But apparently they still fit a three year old when he's not wearing a diaper. One day after rest time, I discovered him with them on. He's worn them a few times since--including once at night time when my brother-in-law was watching the boys so we could go out for my wife's birthday. Nils must have coaxed him into letting him wear them to bed. Somehow the diaper still fit underneath. Don't worry--we haven't let him wear them out in public. But that doesn't mean he won't try.
