My son would get mad and bang his head on the ground. He would do it on carpet, tile, anything. He never seemed like it hurt. I was concerned, because it didn’t seem right. He was banging his forehead on the ground!?!?! I told my pediatrician, who I love and he didn’t seem to concerned about it. My son is now 4 years old and at 3 we put him in preschool for the first time. I am a stay at home Mom. The preschool was concerned about his aggression and behavior. He’s not a bad kid, but he’s compulsive. They suggested I have him tested, which we did and he’s border line Autistic, OCD and ADD. WOW! I never thought of having a kid that was going to have problems like that. They wont label him yet, which is good. We currently have him in an Elementary school ESE program which started this year. They seem to be positive about being able to redirect him and help out. I don’t tell most people my sons problems because once I mention Autistic people seem to think he’s handicap or something. He looks like a normal child. If I were in your shoes I would take your daughter for tests. The tests are with behavior specialist and speech therapist, all they do is play, observe and interact with your child. The behavior specialist goes through little tests with your child, the test are on paper mostly to test your child’s IQ. There’s no needles or anything. Fiddlers is a state program and they paid for everything for me, which helped because I have a PPO and this is very expensive. The earlier you can catch this the better and this process takes just about a year. If you have any questions please ask, I’ll help you with anything.
