Hi, just wanted to find out if I was being unreasonable. Our au pair usually babysits twice a week (including once at the weekend). However, we agreed before she started that she would babysit on Saturdays once a month. She actually hasn't done any babysitting at all for the past month. Her parents came to see her last weekend and she was off from Friday evening until Monday late afternoon (when they returned home). Her friends are coming next weekend and I've asked her to babysit on Saturday evening and she's upset about it (she'll have Friday and Sunday evening free). As she rarely babysits am I being unreasonable to ask her to give up her Saturday evening this time round (it would be the second time this year)?
