At least 50 babies are now known to have died in infant inclined sleep products such as the Fisher-Price Rock ’n Play Sleeper, raising the death toll from the previous count of 37, according to a Consumer Reports investigation.

Though Fisher-Price and Kids II have recalled their inclined sleepers, several other manufacturers continue to sell similar products that pose the same risks.

Infant inclined sleepers are designed to have babies sleep at an incline between 10 degrees and 30 degrees. All such products increase the likelihood of airway compression and suffocation, according to the American Academy of Pediatrics. And all run counter to recommendations from the AAP, the National Institutes of Health, the Centers for Disease Control and Prevention, and the federal Maternal and Child Health Bureau. These organizations say babies should be put to bed on their back—alone, unrestrained, and on a firm, flat surface free of bumpers and other soft bedding.
