The CPSC, US Consumer Product Safety Commission, has found 14 deaths linked with sling-style infant carriers. In 2009, while three infants died, 12 deaths involved babies under 4 months of age. Babies with low birth weight, who were prematurely born, or babies experiencing breathing difficulties owing to issues like a common cold, are at a greater risk.

The CPSC has released official guidelines on the right way to use a sling carrier so that babies do not feel suffocated. Moreover, 3 baby sling devices have been recalled by the CPSC due to manufacturing issues.

Infant baby slings are prone to two suffocation risks. Due to weak musculature, babies are unable to control their heads in the initial few months of life, so there is a chance that the sling can press against the nose and mouth. This can bring about suffocation within one to two minutes. In addition, the sling may rest the baby in a bent position with the chin bending toward the chest. In this situation, air is limited and the baby cannot cry for help while gradually suffocating.

The CPSC recommends, “Parents and caregivers make sure the infant’s face is not covered and is visible at all times to the sling’s wearer. If nursing the baby (is) in a sling, change the baby’s position after feeding so the baby’s head is facing up and is clear of the sling and the mother’s body”.
