Co-Sleeping: Risks and Recommendations for Parents
Co-Sleeping Safely: Risks and Practical Tips for Parents

Co-sleeping with your baby can be a conscious choice or something that happens naturally during those long nights. While it can foster closeness and make nighttime feeding easier, it’s important to recognize that co-sleeping comes with certain risks, such as Sudden Infant Death Syndrome (SIDS), suffocation, and sleep-related accidents. These risks are especially significant during the first year of life.
If you choose to co-sleep with your baby, taking steps to make it as safe as possible is essential. The key is to create an environment that minimizes potential dangers.
How to Create a Safe Co-Sleeping Space
1. Use a firm, flat mattress
Avoid soft surfaces like waterbeds, pillows, or woolen underlays, as they increase the risk of suffocation and overheating. A firm mattress ensures your baby has a stable and safe sleeping surface.
2. Place the mattress on the floor
If you're worried about your baby rolling off the bed, consider placing the mattress directly on the floor. This eliminates gaps between the mattress and walls or furniture where a baby might get trapped.
3. Keep pillows and heavy blankets away from your baby
These items can accidentally cover your baby’s face and obstruct their breathing. Opt for light cotton sheets and blankets, and ensure they are positioned away from the baby.
4. Dress your baby comfortably to prevent overheating
Maintaining the right room temperature (around 20–22°C) and dressing your baby in lightweight clothing can help prevent overheating, which is a known risk factor for SIDS. A cotton onesie or a safe sleep sack with open arms is ideal. Avoid hats or extra layers, as babies regulate their temperature better when their head is uncovered.
5. Always place your baby on their back to sleep
Sleeping on their back significantly reduces the risk of SIDS compared to sleeping on their stomach or side.
6. Keep your baby next to you, not between two adults
The safest position for your baby is on one side of the bed next to you, away from the middle. This reduces the risk of your baby’s head being covered by adult bedding and helps prevent overheating.
When Co-Sleeping is Not Safe
Even when you follow all safety recommendations, there are situations where co-sleeping should be avoided entirely:
1. If anyone in the bed smokes, has consumed alcohol, or taken sedatives
Substances like alcohol or certain medications can reduce awareness and reaction time, increasing the risk of accidents.
2. If your baby was born prematurely or has a low birth weight
Babies with these conditions are more vulnerable and require extra care. Room-sharing with the baby in a separate crib is the safest option.
3. If there are other children or pets in the bed
The presence of siblings or animals in the bed can increase the likelihood of accidental injury or suffocation.
4. If you’re using soft or oversized bedding
Heavy blankets, duvets, and pillows designed for adults are not safe for babies. Ensure the sleeping space is free from such items.
5. If the baby is sleeping on a soft or unstable surface
Avoid co-sleeping on couches, recliners, or any surface that isn’t firm and stable, as these environments pose significant risks for a baby.
Why These Guidelines Matter
While these recommendations can significantly reduce risks, it’s important to remember that no setup can completely eliminate them. For this reason, leading organizations like the American Academy of Pediatrics recommend room-sharing over bed-sharing. Placing your baby in a crib, bassinet, or play yard next to your bed provides the closeness you desire while keeping your baby in a safe, separate space.
A Gentle Reminder
Co-sleeping is a personal decision, and every family is unique. For some, it’s the best way to bond with their baby and simplify nighttime care. For others, it might not feel like the right choice. Whatever you decide, prioritize safety and listen to your baby’s needs.
While this article focused on the risks of co-sleeping, safely organized co-sleeping can have its benefits too. I’ll explore these advantages, such as fostering a strong bond and making breastfeeding easier, in my next article.
