Yuck. Yes we have all had the poop on the fore finger happen but that's an accident. To deliberately stick your hand in the diaper is ridiculous and disgusting. I would hand her a wipe and tell her to use it before she touchs anything in my house. If she refuses I would tell her not to touch anything and I would open the door for her. There is no excuse for being this unsanitary. Has she not heard of ecoli?
