Are baby slings safe? The short answer is "Yes." Slings have been safely used for thousands of years.
According the the Consumer Products Safety Commission, in the past 18 years, 14 babies have died in slings. 3 of those babies died in the Infantino Sling Rider, which was recalled in 2010. Over 1 million slings from this company were taken off the market. This sling style is a "bag sling" and it is different from a "ring sling".
This is a picture of the Infantino Sling Rider.
The problem with bag slings is that babies can easily move into unsafe positions.
This diagram from the Consumer Products Safety Commission shows how the sling is unsafe for an infant. Babies can slide into postions where there airway collapses or is blocked. They are also in positions where the adult can't see their face or feel them breathing.

They do not recommend the use of a sling for infants under 4 months.

3. Baby's head is close enough to kiss
