weighted blankets

[vaknitter]

I am wondering if anyone has any personal experience with the use of weighted blankets in infants?
I have joked since my son was born that he would probably sleep great with one and now at 5months old I have decided I am going to make one and see if it helps him sleep at night. He is constantly in motion and the more mobile he gets the worse his sleep is getting. He wakes himself up with every little twitch. He has been in bed for 90min and I have already put him back to sleep twice.

How are weighted blankets made? I never heard of them before. A quick search indicates they're used with autistic children and children and adults who have sensory processing problems. I find this very interesting because I prefer heavy covers on my bed, I sleep better and if I don't have heavy blankets on my legs they often hurt. Anyhow, I don't really know anything about them.

ETA: Has he ever slept well? I think my GS was about 5 before my daughter got anywhere near a full night's sleep and he has Asperger's. I hope you aren't dealing with something like that.
