COOKIE MONSTER EATING DIAPERS!!!! I caught Cookie Monster eating my daughters diapers this morning!!! Gross!!!! At first I thought he was just eating toys, but now hes eating diapers. I thought that he was only eating the clean diapers, only to find he was eating the gross pee-pee diapers too! Time to wash his mouth. My son loves feeding his stuffed animals all sorts of funny things.
