In general, parents should bring their infants to the hospital for checkups 42 days after delivery. If there are special circumstances that prevent timely review, it is recommended to try to do so within 2 months after delivery. Postpartum health checkups should be performed at the delivery hospital 42 days after delivery, including general checkups, such as blood pressure, heart rate, blood routine, and urine routine. If the mother has medical comorbidities or obstetric complications, she should also be examined accordingly. Gynecological examination is also needed to understand uterine rejuvenation, to observe malignant fluid and to examine the breasts. In the pediatric department, a full-body physical examination of the baby is also required. In addition, family planning guidance is required. In addition, after the puerperium is over, i.e., 8 weeks after delivery, sexual intercourse can be performed, and ovulation can occur 42 days after delivery, so breastfeeding patients should use contraceptive devices. For those who are not breastfeeding, the choice of contraceptive method is the same as that for women of general childbearing age.
