The benefits of babywearing and the use of baby slings for nurturing your baby have become increasingly well-known. However,
slings can pose two different types of suffocation hazards to babies. In the first few months of life, babies cannot control their heads because of weak neck muscles and their heads are proportionally bigger. This is even more of a problem for babies who are premature or have been born with a low birth weight. If worn incorrectly the sling’s fabric can press against an infant’s nose and mouth, blocking the baby’s breathing and rapidly suffocating a baby within a minute or two. Additionally, when a sling keeps the infant in a curled or fetal position bending the chin toward the chest, the airways can be restricted, limiting the oxygen supply. The baby may not be able to cry for help and can slowly suffocate. The youngest and smallest babies are at greatest risk.
There are ways to avoid harm. Putting young infants in a vertical position with their heads up high on mom’s or dad’s chest, they are positioned chest to chest and their heads are turned to the side so that their noses and mouths are clear of any obstruction is one way to keep them safe. The makers of baby sling carriers have many safety tips and instructions on their websites. So even if you buy a sling second-hand go to the manufacturers websites and review their safety information and instructions.
