What families have you seen whose wives were separated by their mother-in-law?

Tell a true story, my daughter-in-law gave birth to a child, and I don't know why. (I was not very clear about the situation at that time. The doctor said that he would have a caesarean section and let the maternal husband sign it. Maternal mother-in-law is afraid of her son's signature and won't sit on the ground. She said it was okay for my mother to have several children. This hospital knocked money, (the county hospital may give birth to several thousand yuan, and caesarean section may reimburse two or three thousand yuan), but it didn't sign it anyway. As a result, the adults died and the children lived. I went back to my hometown a few years ago. My dad said that the maternal mother sued the maternal, and the maternal mother was also pitiful. The man died and the mother had no brothers or sisters. Alas. When my dad told me, I was really in a mood. Why did a woman give birth to a child, and her life was in the hands of others, and she didn't raise you? Why?
