I'm not sure what could be wrong with him at this point. The second I walk towards a door or walk out of a room he starts doing this high pitched scream and he does it until I come back. He has been fed, changed, and whatever else I suspected he may need and he's still doing it. I can't get anything done and I had to even tell a woman doing my phone interview that I couldn't talk because my son constantly screamed in the background ... he's literally had a nap and everything ...
