as a baby she used to always scream for no reason, i tried everything to settle her and nothing worked. she has always been quite advanced when she was 2 she could tell you the alphabet, now she struggles too. her speach is good, except she uses her words backwords, like "do it can i mummy". she has always had anger issues for some reason i dont know, ive tried asking her what is wrong and all i get is "i dont know why". Today at school during dinner time, she picked up a dinner tray and hit 2 boys with it and the teacher said she had made a mess of them. i asked her why she did it and again she said "i dont know why" and got frustrated. she keeps getting into my 9 month old sons cot during the early morning, first time she did it i explained to her the dangers and told her not to do it again, she said she wouldnt, but she did second time i asked her what could happen she said told me what i explained, then she did it again but this time put some clothing over his head and around his neck and also put a large toy in there. she also keeps picking him up out of his bouncy chair and laying him on the sofa then walking away from him, she did that the other night while i was running her a bath, then she came in got in her bath then told me connor was on the sofa, i ran into the room and caught him just before he rolled over onto the floor. i have been to the doctors, health visitors, and the hospital with some of this info not all of it ad they told me not to worry, but im very worried ive been fighting this behaviour for almost 3 yrs now and its getting really out of hand now, no one will help me. i love my daughter and want to help her so badly. my gut feeling is telling me she is autistic or there is something not quite right, please get back to me asap. thanks
