http://www.waucondawrestling.org/YC/ycParents.htm I was given an almost identical guide when I first signed my son up for wrestling, I believe from the national USA Wrestling organization. When I was new to the sport several years ago, I found it to be a very good source for information about the benefits of wrestling to the young athlete and as a beginning educational tool for me as a new fan. It also does address the proper starting age question. Hopefully you will be able to get on the site by using the above.
