After Fisher-Price’s Rock ’n Play sleeper was linked to multiple infant deaths, the company and a government regulator issued a joint warning to consumers about the product on Friday, stopping short of a recall.

But on Tuesday, the American Academy of Pediatrics called on Fisher-Price to withdraw the Rock ’n Play immediately. The group’s president, Dr. Kyle Yasuda, said in a statement that the sleeper, which rocks babies to sleep in a cloth-covered cradle, was “deadly” because it could cause asphyxiation.

Fisher-Price, which stood by the safety of the Rock ’n Play and said a recall was not necessary, can keep selling the product. Here’s why.

The potential danger

In issuing the safety alert, the consumer commission said it was aware of 10 deaths since 2015 of children 3 months or older linked to the Rock ’n Play. Each of the children had rolled from their backs to their stomachs or sides while in the sleeper without being secured in the product’s harness restraint.
