I've given up. I have a thumbsucker and all I have to do is say her name and she pulls it out of her mouth after a million times of trying to stop her. My other 1 year old hardly has any teeth so I suppose that's why he's been sticking his fingers in his mouth lately and my 3 year old has always been oral but he's doing much better after a year of me saying nonstop "NOT IN YOUR MOUTH". Yes, I feel like a broken record and have to repeat that over and over every day.

I agree with playfelt, if they are sick I'm diligent with their own diaper wipes to constantly wipe their faces and hands. Hey, the parents can pay for those wipes! If they aren't sick then I'm a little more lax because it's frikking frustrating!
