To answer a couple questions since they've been repeated already.
No, we don't live "in a pig pen" as someone so rudely asked. He has his own room, and dresses himself, and instead of putting his dirty clothes in the basket he throws them around the room. He's 4, not 1 or 2. There's no reason r can't pick his own clothes up. And I know it sounds strange since he is a boy, but he does hate being in dirty clothes. He'll change 2 or 3 times a day if I let him.
I love the responses that he's a "baby" and he's "too young" for responsibilities! Once I told him his time was up and I was just going to do mommy and daddy's clothes, he got up and finished.
