My grandson has several problems including autism, non verbal, self harming, hyper all the time, he will only eat whatsits up to 8 bags a day, he sleeps for anything from 1 hrs to 6hrs and is predominantly up most nights and has lots of meltdowns which he will bite and kick his mum or he'll head butt anything that's near him and he'll punch himself in his face until she tries to hold him to carm him down. He enjoys lining things up eg cars, chairs,hoops etc he's at a special school for 5 hours a day who can't do anything with him, and she has has several conversations with doctors, special needs,and consultation with Sheffield children hospital who can't offer her any more help, because the sleep medication they gave him before, doesn't work now. Is there anyone on mumsnet who has a child with similar issues that could give us some areas where to try and find better solutions before he too strong for her. Thanks
