... a little too much. My neighbours / friends love our great nanny who started 4 months ago, so much that they have started asking her to do ad hoc babysitting as they know my hours are flexible (work at home PhD student). Nanny has said yes once or twice but has very sensibly asked me what I think of it. I am now uncomfortable with the situation as she is getting asked with little notice and already works a 40 hour week for me. Any ideas on how to knock this one on the head without ruining friendships?
