I was just wondering, when I take the children to the park, my mum sometimes comes with me, for an extra pair of hands, she has a CRB check I was just wondering wether this is ok? and can I write this into my park risk assessment?

I would say its no different from meeting a friend at the park. By all means put it in your risk assessment - the fact that she is CRB checked is good. You are ultimately completely responsible for the children though anyway.

You can have anyone as long as they are not left with the children - make sure they are in sight at all times.

Thanks everyone just thought i'd check. She is never left alone she usually has my daughter while I have the others at the park, plus the kids call her nan:)
