Well I only know from my daughter and different things could work for you but she needs heavy touch and heavy work to help her deal with light touch, like using a weighted blanket or wrapping up in one a certain way or exercises they have taught her to compress her joints. Also some of the different therapy swings seem to help. The main thing it does by doing these exercises regularly it helps the light touch feel less irritating and intrusive to begin with. If by chance she is getting too much light touch and is annoyed with it anyway, she will want to do those things to help her cope and that does help some, but in the situation where's she's already been overstimulated by it, it takes a lot longer to help her relax from it. The most important goal is more to find exercises you can do regularly to help so you are not sent into overdrive in the first place.
