agree!!
Remember that: Why you employ a helper? It is because you need her to help you to solve your family problem, not making more problem to you.
Therefore, I never care do she eat or not. I just tell her what food she can eat/cook. And tell me when she almost finish them so that I will buy some for her!
P.S. One day, my yan yan tell me she like the chinese 'dry salty fish' very much.
Then I buy a big 'dry salty fish' for her and she eat it for 2 months !
