It's very hot. The mother-in-law bought a summer quilt for her daughter-in-law. My mother found it covered, and my daughter-in-law was unhappy. We are all family. Is it necessary?

This is definitely impossible. Although it is said that it is a family, it will still be related by blood. Your mother-in-law bought your daughter-in-law a summer quilt, which belongs to her private property. If your mother wants to build it, you can buy him another one. By the way, respect your filial piety, which is equivalent to what someone gave you being taken away by another person. Even your brothers and sisters, you should not be very happy. Then you and your brothers and sisters are also family.
