A weighted blanket might help.

I recently went to the TACA conference a few months ago. I met 3 moms there that told me they all use Calm & Cool by Spectrum Awakening. It's a white powder you can mix in any beverage or just water. I use that along with Super Seratonin Support. These ones are chewables by the same manufacturer. You can order online. They are all natural. Good luck:)

My 28 yr old non verbal aggressive son was on seroquel which raised his weight and cholesterol significantly .After withdrawl he was unable to fall asleep and became very aggressive .Finally we had to put him on Abilify and he is not aggressive and can sleep at least 8 hrs .He is still adjusting the new med .Its only one month he is on Abilify .So far so good .

Have you been explain the benefits of Abilify,(aripiprazole) there have been several studies on this, my 7 year old son (ASD and ADHD)takes it and has made a wonderful improvement for him.
