I have just registered my 16 year old to be my assistant. ( thanks everyone for the advice yesterday :) )i dont want to increase numbers etc, just I have an extra pair of hands during holidays etc and while she is not at college, especially if they allow me the 2 under 1. (she is at school at the moment leaves in 5 weeks)

I was wondering what extra paperwork I would need? if any, or permissions, I knwo she is not allowed to be left on the premisises unattended until 18 and then she needs her first aid?
Any info appreciated
