For sleep difficulties while breastfeeding, it is important to establish good sleep habits such as relaxation techniques, regular physical activity, and avoiding stimulants like alcohol and caffeine. Going to bed at regular times, only when feeling tired, and leaving the bedroom if unable to sleep after 30 minutes can also help. If these strategies are not effective, cognitive-behavioral therapy for insomnia with a therapist may be helpful. While few natural options are safe while breastfeeding, over-the-counter medications like diphenhydramine may be considered, but should be used cautiously and only for short-term relief due to the risk of dependency and potential effects on the infant.
