How to Practice Safe Co-Sleeping with Your Newborn?

Hello there, lovely parents! Today, we are delving into the beautiful, yet often misunderstood, world of co-sleeping. Co-sleeping, or sharing your sleep environment with your newborn, can be a delightful bonding experience, but it must be approached with utmost caution. Here’s a comprehensive guide to help you navigate the co-sleeping journey safely.

Understanding the Co-Sleeping Spectrum

Co-sleeping encompasses bed-sharing (baby sleeps in the parent’s bed) and room-sharing (baby sleeps in the same room but on a separate surface). Room-sharing is recommended by the American Academy of Pediatrics (AAP) for at least the first six months as it is associated with a decreased risk of Sudden Infant Death Syndrome (SIDS) Moon et al., 2016. Bed-sharing, however, requires careful consideration due to associated risks.

Setting Safe Co-Sleeping Boundaries

Safety in co-sleeping starts with establishing boundaries. If bed-sharing, use a large bed with a firm mattress and minimal bedding. Loose pillows, plush toys, and blankets should be avoided as they pose a suffocation risk Task Force on Sudden Infant Death Syndrome, 2011. Your baby should sleep on their back and not be near the edge of the bed where they could roll off.

Dressing for Safe Co-Sleeping

A baby’s thermoregulation differs from adults. Dress your baby according to room temperature, not under-the-covers temperature. Overheating is a risk factor for SIDS Moon et al., 2016. Consider a sleep sack for warmth without the hazard of loose blankets.

Duvet Dangers

Dense or heavy bedding can pose a suffocation risk. Opt for light blankets instead, ensuring they’re kept away from your baby. You too should dress lightly to prevent overheating your baby with your body heat.

Sobriety and Smoke-Free Environment

Never co-sleep under the influence of drugs or alcohol, as these can impair your awareness Blair et al., 2014. Exposure to smoke increases SIDS risk and harms a baby’s health in general Vennemann et al., 2008.

The Bed’s Exclusivity Rule

The bed should only be shared by parents and the baby—no siblings, pets, or other individuals Ball et al., 2018. This decreases the risk of accidental suffocation.

Safe Sofa Rule

Never co-sleep on a sofa or armchair. These spaces present a high risk for sleep-related incidents Carpenter et al., 2004. If you feel drowsy while holding your baby, move to a safe sleep surface.

Swaddling Safely

If you swaddle, ensure it doesn’t interfere with breastfeeding or cause overheating Pease et al., 2016. Stop swaddling once your baby shows signs of rolling over to prevent them from rolling onto their stomach while swaddled, which can increase the risk of SIDS Moon et al., 2016.

Co-Sleeping Aids

Several products are designed to make co-sleeping safer. Bedside bassinets or co-sleepers offer a compromise by providing a separate but close space for your baby. Before purchasing any sleep product, make sure it meets the safety standards of reputable organizations such as the Consumer Product Safety Commission.

Being Alert to Changes

Lastly, always be alert to changes. As your baby grows, their sleep patterns and behaviors will change. Always adjust your co-sleeping strategies accordingly to ensure they’re suitable for your baby’s developmental stage.

A Balancing Act: Attachment and Safety

Co-sleeping can be a rewarding way to foster attachment and make night-time parenting more manageable, especially when breastfeeding. Yet, the decision to co-sleep must be balanced with safety considerations. Always follow evidence-based guidelines and consult with your healthcare provider to make the best decision for your family. Happy cuddling!
