CMV: If your child injures my child due to reckless behavior that went uncorrected because you, the parent or guardian, were sitting far away and not paying attention, you are responsible for any damage done, especially any serious injuries.

I've got a 2 year old daughter and we've been to all sorts of parks. I also have a 6 month old, so sometimes I can't be directly next to her on the equipment, but I'm always near. I've seen many many unattended children and the bigger the child the easier to accidentally or purposefully move smaller children. We haven't had any serious injuries or falls, our worst fall was caused by herself anyway, but if a child whose gaurdian wasn't paying attention caused her to fall and break her arm or something, I feel that the adult would be wholly responsible. Children don't have fully formed brains or impulse control, that's why they need us there to tell them safety rules. If on the other hand the other gaurdian was actively there and trying to curb dangerous behaviour and an accident occured, I wouldn't blame anyone.

This can just be extended back at you. If you were near your child, you should be able to stop anything before it blows up or at least mitigate any damage.

If you couldn't stop it, than there is no reason to believe if the instigator's parent would have either.

If you are always able to stop it, then clearly injury would only happen when there are 2 absent parents.

There is of course the question of *when* a child stops needing a parent guardian. Should one not give a 10 year old some room, as they need to develop independence? Should the parent still be liable?
