20 month old grandson very very bad
I havee a 20 month old grandson and sometimes I think he should be tested for I dont even know, something. lets start he still wakes up about 4 times in the middle of the night it takes a very long time to put him to sleep and when he sleeps he twitches alot. He doesnt talk much, he says one to two word sentences only, he bites all the time we cannot keep him alone even with his older brother. he is very very hyper, my daughter is exhausted, she has tried everything from time out to no toys. I have never seen a child act like this. His brother has bruises from him hitting him with objects. When he gets mad he screams very loud and sometimes hits himself and or bangs his head. Is there possibly a medical problem his doctor says he is fine but they havent tested him for anything, dont know what to do????
