I raised 4 sons, and I always understood that rough-housing is important in a boy’s development. Encouraged them to climb trees, skateboard, and play any sports that interested them — soccer, lacrosse, baseball, basketball, but I drew the line at football when they were young.
My eldest boy wanted to play, but I made him wait until high school. Of course, at that point, he was nowhere near the level of the boys who had been playing since 1st grade, so he was a bench warmer in 9th grade, and then he was over it. All part of my plan....
BTW, something a lot of people don't know: Soccer has almost as many concussions as football. Also, cheerleading is by far the most dangerous sport for women.
