We have 3 boys going from our club to 6 under state. I wish we knew the clarification because for example my son weighs on average anywhere from 37.4 to 38.4.Never more then 38.4. I put him in the 40 lb weight class because I don't know how to explain to a child they can't wrestle if they don't make weight. Our other 2 wrestles are the same way so we moved them up a weight class. Is it to late to change their weight classes? Just asking new at some of this.. thanks
