You might also want to try some gentle but firm squeezing pressure on his joints before sleep time. It's pressure, not at all tickly, and if you go too lightly it WILL feel tickly to many people, to firm squeezes usually work best for this. I would start at J's feet and work my way to ankles, then knees, hips, shoulders, elbows, wrists, fingers (one whole handful of fingers at a time, then thumb separately). It really seemed to help "ground" her, and even now we still do this at bedtime.
