there is a fine line of course but I think that you have to remember no matter what he is your son and you want him to think the best of you.
Give praise and push him or her to be their best. If you keep thing positive and a loving learning relationship that is best for all involved.
So next time that boy/girl gets beat say- holy cow bells batman that kids was good today- you will have another chance so keep working hard. You are almost there
