Is it OK for a divorced woman who is breast-feeding to have no children? According to Article 1 of the Several Specific Opinions of the People's Court on Handling Child Support Issues in the Trial of Divorce Cases issued by the Supreme People's Court on November 3, 1993, "Children under the age of two generally live with their mother". If the mother has one of the following circumstances, she can also live with her father:
 (1) Having infectious diseases or other serious diseases that cannot be cured for a long time, and children are not suitable to live with them;
 (2) Having conditions for upbringing but not fulfilling the obligation of upbringing, and the father requires the child to live with him;
 (3) For other reasons, children really cannot live with their mother. To sum up, if the woman who divorced during lactation meets one of the above three factors, she may not have the custody of the child. However, in principle, divorce is not allowed during lactation in China, unless one party has fault liability, especially the man is not allowed to initiate divorce. Judging from the fact that it is conducive to the growth of children, it is highly possible to award the woman.
