As a working mum, I rely a lot on my helper. But recently she has reduced the menu at home to the same 5 dishes day after day. I am too busy to cook, and I really can't have her leave right now. What do I do?

I would definitely come up with a schedule of meals for her to use. You could even ask her if she wants to try out cooking something new and try out different recipes. I'd suggest buying her some simple recipe books that she can use :)
