Live with your mother-in-law. If she is responsible for cooking, respect her labor. Actually, cooking at home is also very tiring. If you want to cook well, you can't repeat it. You have to mix meat and vegetables and save money. If the mother-in-law does well, she can take her family out for dinner during the break, give the old lady a holiday and eat something delicious by the way. If my mother-in-law resigns, she won't have time to cook. Then you can only hire a nanny.
