Hi, My name is R. from Zanesville and I wanted to tell you that her behavior is quite normal and I see u have gotten a few responses. I agree with others that if she does bang her head when she goes else where, it probably is a soothing technique, but you DID say she does this at home too so I got to thinking... it probably isnt just a soothing technique. You see the reason i say this is because I am 36 yrs old now and have banged my head, while on my stomach, since i was 1 yr old and continue to do so even to this day! (Only while I am asleep) Drs said I would outgrow it but i never did. FInally I found someone who would listen to me, after many yrs of sleepless nights and tired mornings, a dr told me i needed to be put on an anti-seizure medicine called neurontin or also called gabapentin. Now mind u i am not having seizures when i bang my head, they just found this med would work. To this day, I have never banged my head since! (they first tried me on depakote, but was allergic to it) Now i know your daughter is young but get a few opinions and if u have to, print out what i have written and take it to the drs with you. Like others said though, she may outgrow the banging of her head...I don't know. I would definitely speak it over with her dr though for I am not a dr. I sure hope my information helps you somewhat. I'd be interested in knowing how things go for you. Keep me posted will you? Hugs and take care.
