Hi hkc123 it sounds to me like you need to be a little more forcefull with your little one dont allow him to touch his diaper tell him only mommy is allowed to change him and that he will be spanked if he does it again. My little knows that if she removes her diaper before daddy can check her she will get a good paddling...Sometimes i get an issue of parenting magazine and use the articles to help me with my little one.
