Its a proven therapy for Autism - I googled it after My SIL asked me - apparently (some) Autism patients get comfort and are able to sleep once they have this (quite heavy) weight on top of them!
I planned to either sew pockets and/ or make little pakages of beads and sew them in lines - you concentrate the weight in the centre - on top of the patient!
He is 14.
I have read that patients like upto 20 lbs in weight!!!! For a child the recommendation seems to be 10% body weight plus a pound.
So no suggestions where to get the beads then?
I have read that you can use sand, gravel, popcorn or lentils - rice etc - but these are not washable! Although they would be alot cheaper!!!
