Hi, It has been a while since my last visit. I have a first grader who is displaying odd, even unsafe, behaviors. I am trying to determine the cause of this behavior. First of all, he eats everything: crayons, playdough, paper, erasers, parts of pencils, literally anything that is small enough to fit in his mouth. I have talked to his mom and she is not overly concerned. He does not simply chew on it, he swallows it too! Last week he started sucking on his arm. He will suck on it until he has a raised welt. He told me he is trying to make it bleed. Today he kissed and licked the toilet in the boys restroom. Each time one of these things happens, I correct him, act appalled, take away what ever is in his mouth, try to explain why the behavior is unhealthy or unsafe. I have also called his mom several times. She is never overly concerned. I have had the counselor talk to him a few times but the behaviors continue. I am just really concerned about this little guy. I mean, is this kind of behavior a sign of abuse or something. I have tried googling these things but came up empty handed. Has anyone ever had a student with this kind of behavior? Did you know what caused it? How did you get it stopped?
