This right here. I think a lot of people are getting caught up in notion, that they have to be competing at age 4 and competing all the time sometimes two tournaments a weekend, to be a good wrestler later. The tournaments should be about the experience at youngs, from 4 up to say around 10-12. Take them to a few meets, let them hang out with teammates and build a bond early with each other. Even if they lose both matches right off the bat, let them hang out and cheer on their teammates for a little longer.
Once they start approaching middle school age level, if you ask them if they're ready to step up and they are, then let them start cranking out tournaments left and right. You don't want to burn them out before they even get there though. Make it fun for the little guys and quit worrying about getting them 40+ matches. How many guys have we seen recently have very little experience prior to HS and still doing well at IHSAA State Finals?
Let them be kids and gauge their mental capabilities on how much they can handle once they start getting into the middle school age.
