Pooped in the Potty

I'm sure you don't want to know this, but I'm going to tell you anyway. Aiden pooped in his little potty today! He loves running around naked, so I decided to have naked time every night (Aiden, not me). Yesterday I let him run around naked and Steve was worried about him peeing in our living room. He brought Aiden's potty in the living room and Aiden sat in it. He started grunting and farting. Then he got up, smiled and started running around. He sat in it again and did the same thing. After Aiden stood up, Steve looked in the potty and saw that he pooped (I'll spare you the picture I took)! I told daycare and she said that he always pulls down his pants and maybe he's telling her he has to go potty. He understands the concept...
