Babysitting... to do or not?

I provide a babysitting service for my mindees primarily. If I am unavailable to babysit I have two other trusted childcare workers I highly recommend. One is a qualified primary school teacher (my sister!) who is currently nannying, and the other is an OFSTED registered childminder. They both live locally to me.

I am actually so busy thouhg - I am keen to help the parents, but aLSO KEEN not to, if that makes sense? At least I can pass the work onto others...
