Potential Danger of 'Bag Slings'

"With the majority of fabric carriers it takes only a few minor adjustments to get baby safely and comfortably positioned however, it appears that ‘bag slings’ (like the Infantino SlingRider, Lamaze Close Comfort, etc.) have several significant design flaws that could place an infant at risk of respiratory distress or oxygen deprivation.

First, the design of these bag slings causes baby to curl chin to chest, larger babies more so because their heads are positioned further up in the carrier. This position kinks baby’s airway causing the baby to work harder to breathe.

For more information on the importance of maintaining an infant's head and neck in an aligned position see the articles:

Second, bag slings are roughly triangle shaped; flat bottom and two sides that slant upwards toward the elastic top. This “triangle” means that the pouch fabric is always angled very close to the sides of baby’s face. If baby rotates even slightly he ends up with his nose within a ¼” of the side, or even pressed against the side of the pouch. Once baby has his head pressed against the side of the carrier and/or against the parent's body there is a risk of him becoming oxygen deprived or even suffocating.

Third, it is difficult for the parent to closely monitor their infant unless he/she pulls open the top of the sling. Bag slings are generally deep, plus they sag when baby is placed in it, further increasing the depth of the carrier. The gathered top, and the fact that the sling hangs so low, obstructs the parent’s view of baby. If a newborn were to have difficulty breathing, and/or rotate until his nose and mouth was pressed against the side of the carrier, the parent may not be aware of the baby’s respiratory distress for some time. Compounding this problem is the difficulty of feeling the baby's distress through the thick fabric of the sling.

Fourth, although one bag sling is designed with large mesh panels placed near the infant’s head, others are not. There is a possibility that, with only a very small opening at the top of a non-mesh sling, an infant may not receive adequate amounts of fresh air. There is also the concern that carbon dioxide levels could rise the longer the infant remains in the sling.

Compare bag slings with a shallow fabric pouch or adjustable open-tailed sling (or mei tai or wrap). In these types of carriers an infant is easily monitored and visualized. Also, a newborn's head is effectively sandwiched between the sides of these carriers, preventing the infant from easily rotating his/her head into the sides of the carrier."

Please, please seriously consider before you purchase a 'bag sling'. The last I saw, these slings are promoted as "NEW!" and "MUST BUY!" in our Malaysian market.

Read more on the different tests being done on these slings. These are definitely worth a read especially if you are planning to buy a 'bag sling' (more so if you already own one)
