At my son's school the parent helper who takes the sessions regularly joins in with their football games/matches if they have odd numbers ie to make the teams even. He is very enthusiastic ( read that as competative) and I worry that one of the kids will get hurt by accident. ( A Yr 6 child got a ball in the face last week full pelt) Just wondered what the guidance is on this. Is it ok? Is it legal? and what would happen if a child got hurt... Fairly sure I know what the answer is but wondered what you all thought.
