Exactly!!!! My yan will arrange her meals. She can buy whatever food she likes provided that it's not expensive. Don't need to think too much, otherwise, they will take advantage of your kindness!!!!!! I think it's not necessary to treat them bad or good, reasonable is sufficient. If they do sth wrong, u must point it out. Don't think it's embrassing or too concern their feelings. I've fired 2 maids in 1.5 year. This is my experience. You must let her know that you are her mum and must respect you.
