Class II - Moderate
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. The sling's fabric can press against an infant's nose and mouth, blocking the baby's breathing. Additionally, where a sling keeps the infant in a curled position bending the chin toward the chest, the airways can be restricted, limiting the oxygen supply. The baby will not be able to cry for help and can slowly suffocate.
