Nursing mothers probably experience insomnia less frequently than other mothers. The hormone, prolactin, that is released during breastfeeding aids a mother's relaxation. It has a very calming effect. Prolactin levels are highest at night, so mothers who nurse their babies during the night are getting larger doses of this relaxing hormone. This helps them to return to sleep more quickly during those nighttime feeds.
Insomnia is a common reaction to stress.
Practice meditation and progressive relaxation for 15 minutes each day. Rest when your baby rests during the day. It may be harder to go to sleep at night when you are overtired. Ideally, avoid eating heavily for at least four hours before bed. Treat yourself to a warm, relaxing bath before climbing into bed.
