On the Issue of sleep


Published recently in the journal Pediatrics, researchers report that they found no difference in the amount of sleep a mother receives whether she is breastfeeding or formula feeding her baby.  In their study, 80 new mothers were monitored electronically over a ten-week period beginning at 2 weeks post-partum.  Additionally, the mothers completed daily diaries.  Researchers measured total sleep and time awake, sleep quality, fatigue and daytime sleepiness.  In addition to finding no difference in the amount of sleep, the researchers found no difference in fatigue or daytime sleepiness.
The fact is many of us have long believed that breastfeeding mothers get as much sleep (if not a little more) and perhaps a better quality of sleep than their formula feeding counterparts.  One reason may be that when we breastfeed, the hormone relaxin is stimulated and released from our brain.  Relaxin helps us to feel more relaxed.  So, we tend to fall asleep very easily after feedings, nature’s way of encouraging rest for a new mom.  Furthermore, little effort is required to bring baby to breast when he awakens for a feeding.  And the milk is already warm and waiting!   No formula mixing, warming, etc. is necessary.  More time to sleep!  Finally, breastfed babies tend not to over-feed or take in large amounts of air during feedings, so they are not prone to the discomforts of stomach distention and aerophagia commonly seen in formula / bottle-fed infants.  In the event you’d like to read more, I have added a couple of links to more information about the study.  However, please don’t lose valuable sleep over this.  Remember the old adage “sleep when your baby sleeps” and you should be fine!
Happy Sleeping!
