Daughter-in-law gives birth to children regardless of her mother-in-law. What is the mother-in-law's psychological state?

The law does not stipulate that the mother-in-law bears the responsibility and obligation of the daughter-in-law. Whether he will go or not depends on whether he wants to go or not.

If you get along well, your mother-in-law will take care of you. How can a mother-in-law be unhappy and desperate to serve her grandchildren?

You should review your own shortcomings first, not find fault with your mother-in-law.
