I have a little girl in my class who has done pretty much every gross thing you can think of. I am a teacher so things like boogers and snot, and spit and vomit are no big deal. I am also a preschool teacher so poo isn't that big of a shock either. But when a child is poking her finger behind her to taste it, sticking her head in the toilet, licking things off the table and floor, reaching "down there" and licking her fingers.. I have to admit I have been unable to hold my lunch back. Her parents don't seem to think its an issue. I am concerned she may have some developmental delays but nothing major. She seems to come from a family that doesn't seem to care about a lot of things that have to do with her and frankly I think they are just sick of her in general. I finally got the mother to agree to have her tested for speech. But I am not sure how to relay this message to the child that these things she is doing is gross and dirty. We try to explain it to her but we cannot hold her attention for more than a few seconds and everything goes in one ear and out the other. Any suggestions on how to help her? Or how to help her parents realize this is a problem?
