According to Ren Xueqin , prenatal education includes the knowledge of preventing postpartum depression and the difficulties that may be encountered in the process of changing the role of mother. If the mother has post natal depression, her husband or relatives should communicate with her and give her support and trust. If you have a friend who has suffered from this disease before, you can contact more friends, learn from them, and further help yourself recover. Improve coping and stress management methods, conduct relaxation training, and enhance self-confidence. Do a good job in the guidance of prenatal newborn care, reduce the psychological pressure, explain the benefits of breastfeeding, and cultivate the feelings of mothers and infants.
