No Because doctors should respect patients' privacy, they should not tell patients' privacy to anyone other than themselves unless they get patients' consent. Although his wife is his family, she has no right to invade his privacy. The child is not his own. There are many answers to this question.

But morally speaking, it is necessary to tell the husband that the child belongs to both sides, and the husband has the right to know the information of the child, although it is not his own.
