All models of the Fisher-Price “Rock ‘n Play” sleepers that have been blamed for a number of infant deaths have been recalled, according to the U.S. Consumer Product Safety Commission.

The CPSC said about 4.7 million products are affected by the recall.

“Infant fatalities have occurred in Rock ‘n Play Sleepers, after the infants rolled from their back to their stomach or side while unrestrained, or under other circumstances,” the CPSC said.

According to the CPSC, over 30 infant deaths have occurred in the sleepers since the product was introduced in 2009.

Consumers should stop using the sleepers and contact Fisher-Price for a refund or voucher, the CPSC said.

Fisher-Price has provided instructions to consumers to return two specific parts from the sleeper called the hub assemblies. The company said the parts may have an auto rock motor attached depending on the version of the sleeper.

A prepaid mailing label will be sent to consumers from Fisher-Price. The company said consumers should either include the original purchase receipt or write the month and year of purchase on one of the hubs.

Those who have owned a sleeper for six months or less will receive a full cash refund while those who have owned the product for longer will get a voucher that can be redeemed for a new product.
