Co-sleeping, or bed-sharing, is when an infant sleeps in the same bed as an adult, typically the parents. It is considered a risk factor for Sudden Infant Death Syndrome (SIDS) because it increases the likelihood of accidents and suffocation.
The following are some reasons why co-sleeping is a SIDS risk:
1. Soft bedding: When infants sleep in the same bed as adults, they are at risk of suffocation from the soft bedding such as pillows, blankets, and comforters. These can block the baby's airway or cause them to become overheated.
2. Overlaying: Adults may accidentally roll over or lay on top of the baby while they are sleeping, which can cause suffocation.
3. Obstructions: Infants may become trapped between the bed and the wall or between the bed and the headboard, which can cause suffocation.
4. Environmental factors: Co-sleeping can increase the risk of accidents such as falls, suffocation, and fire.
5. Other factors: Some studies have shown that co-sleeping is associated with an increased risk of SIDS in infants who are exposed to cigarette smoke, who have a low birth weight, or who have been born prematurely.
It's important to note that the American Academy of Pediatrics (AAP) recommends that infants sleep in the same room as their parents, but on a separate surface, such as a crib or a bassinet, for at least the first 6 months of life. This can reduce the risk of SIDS by as much as 50%.
