A little pretext: My Son is 5 (soon to be 6), he started tball this spring and enjoyed himself a lot. Since it's been over I've been debating what I want him to do next.  I've asked him about wrestling, BJJ (or "Karate" as I tell him), soccer, basketball and flag football.

He doesnt really have much of an answer except he wants to wrestle and do "karate" with me. I'd really like him to get involved in football but I am honestly worried about the full contact/hits to the head. Body injuries don't bug me, it's the CTE and concussions that do. 

So my question is what have other parents done? What helped sway your decision, etc? All input would be appreciated. 

Mods: Not sure if this belongs in "other sports" or "anything else" as it sort of pertains to both.
