Coaches touch our children all the time. If we are not at every practice and see every game/match we have no idea what goes on. In public when our children are touched THEN we have a chance to respond. I don't believe this coach meant to harm your child but rather teach who he was coaching a lesson . As parents we allow our children to participate in all kind of sports. What comes with that is someone having a huge influence over our child's life. If we, as parents, have a problem with it then we need to approach that coach with respect. It is very simple...just tell the coach or person you have a problem with in private you did not appreciate what went on. AND be careful, we as parents put our children on display and just because what goes on is not to OUR liking...ask the child how THEY felt. You could gain incredible insight.
