Postpartum Care: An Approach to the Fourth Trimester.

The postpartum period, defined as the 12 weeks after delivery, is an important time for a new mother and her family and can be considered a fourth trimester. Outpatient postpartum care should be initiated within three weeks after delivery in person or by phone, and may require multiple contacts with the patient to fully address needs and concerns. A full assessment is recommended within 12 weeks.
