Leave him alone for 10 minutes and what do you get???

Ok, so my little guy was extremely crabby the other day... I put him down for a nap, nothing unusual there except that he went down without a tear or anything, right to sleep and woke up a couple of hours later in a VERY good mood. Austin and I were in here playing a game on the computer and we heard Luke wake up, we left him in there since he was being quiet and playing with the toys he had in his bed (or so we thought) Anyway, 10 minutes go by and I tell Austin, "why don't you go ahead and bring your brother in here" Austin goes to the door and the only thing he can muster to say is "UM MOOOOOOMMMMMMM" I ask him if Luke had stunk up his room again, Austin says "UMMMM NOOOO, its much worse" I walk in there and Luke is stark naked, diaper off and poop all over his crib, his sheet, the wall. Um, yeah, much worse ... Needless to say, Luke will not be going to bed in only a diaper EVER again, and if he does, we won't be leaving him for 10 minutes to play nice.... Oh fun!!
