The puerperium period is 42 days, after the puerperium period, the mother’s body organs almost completely recovered, at this time, couples can share the bed. 2. Cesarean section: If a woman has a cesarean section, the recovery time will be prolonged due to the fact that cesarean section itself is a traumatic surgery that causes more damage to the mother’s body. Although the puerperium after the body organs can also be restored to the state of non-pregnancy, but the wound recovery still needs a period of time, three months or so basic healing, so the child can be cohabitation after 90 days! It is recommended to pay attention to the postnatal period to supplement nutrition, avoid excessive coitus, and maintain good habits in order to recover as soon as possible.
