My stepson is almost 7 years old, but he still talks and acts as though he is 3. He does not wipe himself after using the bathroom, constantly has his hands down his pants (which accounts for the poop caked under his nails), poops his pants, cannot brush his teeth, cannot eat without getting food all over him, drinks chocolate milk so fast he throws up at the dinner table, will not look at you when you are speaking to him, doesn't like to be hugged, forgets that he's not supposed to do something 2 minutes after you tell him not to do it, etc, etc. I think he is slightly autistic, but there's nothing I can do about it. His biological mother babies him to no end, and she thinks these kinds of things are "cute." If either my husband or I were to suggest that he should be screened, she would have a fit. If I knew my stepson had some kind of disorder, I think I would handle his disobedience and his slow rate of learning much more in stride. Right now, as bad as it seems to say it, I am relieved when he goes home at the end of the weekend. I get so frusterated with him and I don't want to be the "evil stepmother" who is always yelling at him.

Does anyone have any advice or similar experiences?
