All the other kids are in bed (or at least their rooms.) I could tell Buster was messing his pants behind the chair I was sitting in. I go to change him and its up his back. It looks like he has smeared it on something, so I call for husband to find and clean up the smear while I shower a Buster. I get done and husband says he didn't find anything. I sit back in the chair and diaper Buster. The metal vent is out of the floor and there is a paper stuck in there. I pull the paper out and there is a big blob of poop on it. I tell husband. He just sits there in the kitchen. I start yelling at him to come get Buster because he is wiggly and I'm trying to keep the poop away from him. I throw away the paper and get a cleaning solution. There isn't any visible poop anywhere else. The inside of the vent smells like it so I dump some simple green down it. How did he get it down the vent on that paper and no where else? Not on his hands, not on the sides of the vent, or the carpet by the vent. I have to admit I was mad at him for a few min. Poor Buster. I'm sure what ever he did was not intentional. Still its just yucky.
