I wonder if you could say that you don't want your child to be looked after by a stranger. Surely that's your right as a parent, even if they are registered childminders. Especially lately with all the scares about paedophiles getting jobs in schools, and those little babies/children being raped etc.
I know that if I was called up for Jury Duty, I wouldn't want to have Lydia looked after by a stranger...I'm very wary about that sort of thing. I wonder if they can force you to, I hope not!
sorry that was a bit OT, it just got me thinking.
