However, postnatal women may be exposed to similar practical challenges with sleep and infant care postpartum, but some may develop larger sleep problems than others or be more vulnerable to these changes. Among postpartum women, there may not be adequate time and opportunity for sleep the newborn baby requires attention and will disturb maternal sleep in the first months after delivery. Insomnia is defined as repeated difficulty with sleep initiation, duration, consolidation, or quality that occurs despite adequate time and opportunity for sleep, and results in some form of daytime impairment. Insomnia during pregnancy may, therefore, influence the risk of postpartum depression. At the same time, the perinatal period is a time of increased risk for depressive disorders. Women sleep poorly during pregnancy and sleep even less in the postpartum period. Insomnia is both a symptom of depression and a separate disorder that may precede depression.
