My 28 month old grandson woke up from his nap and when his mother went into his room she discovered he had pooped his pants and had some on his hands and face as well as on parts of the bed and floor. He is potty trained and has pooped in his sleep before, but never before had "played" with it. There was no yelling or spanking, just my daughter cleaning the room and me giving him a bath. He does have a new baby sister 11 days old. How should we handle this going forward in case it happens again?
