Adjusting to "The Vest
My daughter didn't start with a vest until she was about 17 years old and she is still not able to take the higher settings two years later -- I don't know off the top of my head but I'm thinking she is down in the single digit numbers like 8 or 9 -- I'd go ahead and turn it down to a more comfortable setting - it still has to be more helpful than nothing and especially at this age, you don't want to start her off associating doing the vest with pain.
