I know what I’m about to say may make me as unpopular as diaper rash with some of you. But I hope you’ll bear with me, because the decision to bed-share with your baby or not is a critically important one.

What is Co-Sleeping With a Newborn?

Co-sleeping (or bed-sharing) is as old as the hills. From our earliest days, parents and babies have slept together for protection, warmth, and convenience. And this custom is growing in popularity: The number of bed-sharing families more than doubled between 1993 and 2000. Dr. Fern Hauck of the University of Virginia reported that 42% of US families bed-share at 2 weeks, 34% at 3 months.

However, many tragic deaths have been linked to the “family bed.” For that reason, scientists have spent a great deal of time evaluating if—and how—babies can safely bed-share. And some concerning results are emerging.

What Happened When Bed-Sharing Families Were Filmed

In one British study, researchers reported that most bed-sharing babies had their mouths and noses covered with a blanket or sheet at some time during the night. A third of the sleeping moms also accidentally rested an arm or leg on their babies.

New Zealand infant sleep researchers, led by Sally Baddock, further confirmed the face-covering risk when co-sleeping. In a study videotaping 80 infants (40 in cribs and 40 bed-sharing), the faces of the bed-sharing babies were obstructed a total of nearly one hour per night! Typically, the mom or baby cleared the blanket away. But a quarter of those who experienced head covering awoke in the morning, still under bedding. That’s pretty unnerving.

Baddock also found that bed-sharing babies fed 3.7 times more often during the night, and that a quarter of the dads ended up moving out of the bed. And, most disturbingly, these babies spent on average 5.7 hours a night lying on their sides (not their backs, which is a safer position). One bed-sharing baby rolled all the way to the stomach.

More Research on Co-Sleeping With a Newborn

Does bed sharing increase the risk of SIDS? Studies from Germany, Holland, and Scotland have found that bed-sharing is connected to an increased SIDS risk for babies under 3 to 4 months of age (and even older, if the parents smoked cigarettes).

On the other hand, bed-sharing Japanese babies have not been found to have a higher SIDS rate—possibly because they’re sleep­ing on hard futons. And studies in England, Canada, and the United States found no increased bed-sharing risk with parents who are sober, attentive, and nonsmoking.

My Advice on Co-Sleeping with Newborn

Is there a safe way to co-sleep? After carefully considering all the current studies, most medical groups, including the American Academy of Pediatrics, advise against a baby sleeping in bed with parents. And I agree.

While I love bed-sharing with older children, it poses too many risks for babies during the first six months (or the first year, if your family has elevated risk factors.) I believe the safest choice is to have your baby sleep right next to your bed...not in your bed.
