Hi my daughter is 3 and 1/2 years old, hypoactive and sensitive (like me)
I was told about the surgical scrub brush. I started using this and a very soft baby brush from an organic shop. I bush my daughter on her arms, legs and back and face but mainly her head and she has gone from sleeping till 5am to now sleeping a 12hour sleep. I also play Mozart as well whilst I brush her. I was always a parent who said I did not have time for this, I would not pat her to sleep, but until I started this brushing my daughter spent all night getting out of bed - normally 10 - 20 times a night for approx 2 hours a night. Now I dedicate half and hour to read to her and brush her and then I have the rest of the night free and she gets a great sleep.
Hope this helps
