The advantages of not breastfeeding include that the mother can have sufficient rest, while the disadvantages include that the baby is prone to infections, the mother’s chances of suffering from cancer increase, and it is not conducive to the recovery of the uterus, etc., which need to be analyzed specifically. 1. Advantages: If someone else feeds the baby formula at night, the mother can have a better rest without having to work hard, and at the same time, she can resume her prenatal work earlier. 2. Disadvantages. (1) Babies are prone to diseases: breast milk contains antibodies and nutrients that can enhance the baby’s resistance and immunity, which is conducive to the normal development of the baby. (2) Increase the chance of maternal cancer: pregnant women who are not breastfeeding have an earlier return of menstruation and ovulation, which increases the risk of maternal breast cancer and ovarian cancer. (3) Not conducive to the recovery of the uterus: breastfeeding can increase the mother-child relationship, and the secretion of milk can also stimulate the contraction of the uterus, which is conducive to the recovery of the uterus, so that the uterus will return to normal as soon as possible. Because of the many benefits of breastfeeding, it is recommended that mothers should breastfeed when conditions permit. If during breastfeeding, the baby appears uncomfortable symptoms such as abdominal pain, it is recommended to consult a doctor in time, under the guidance of the doctor, improve the relevant examination, to clarify the cause of the disease, symptomatic treatment.
