You can say no rationally and directly. You have to take care of the children by yourself. Today's parenting methods are not like the old methods in the past. Never let your mother-in-law take care of you for a while and then refuse. It is better to refuse at the beginning than to come halfway. After I got married, I lived in my own home, and occasionally I went to live with my mother-in-law, whether it was when I had my first child or now after giving birth to my second child. When I had a baby, she would help me take care of it for a while when I went to my husband's house. She was quite rude. She didn't know how to bathe the baby or change diapers. When the baby cried, she would only come to me or her son to comfort her. Some time ago, my mother-in-law made a suggestion that she would have to pay her every month to take care of the child. This was even better. I didn’t even have to think about how to refuse. She didn’t want to take care of the child herself, and I didn’t force it.
