I was wondering if a weighted blanket will help my 4 year old ASD son to sleep better. He does move a lot in his sleep, he can wake several times, or just really early and then not go back to sleep. He always kicks his covers off him so a weighted blanket might just really annoy him and be a waste of money. But then it might just help! I don't know.... would love to hear other people's experiences with this. Thanks.
