I don’t think all kids gravitate to team sports, my son prefers individual sports (tennis & biathalon) altho I asked him to continue in soccer this last season just to have to work as a team, as an only child I felt he needed the balance. I did not push him, tho, as his friends from school were playing.
Just doing something inwhich the body moves for entertainment & family time I feel is enough for a start. Mine just started getting bored at my training sessions. I think it is a natural state for the body to feel better when active & this gives the child a chance to realize this on their own. (IMO)
