Fisher-Price announced Friday that it is recalling 4.7 million Rock ‘n Play sleepers.

The recall involves all models, according to the recall notice posted on the U.S. Consumer Product Safety Commission website.

“Since the 2009 product introduction, over 30 infant fatalities have occurred in Rock ‘n Play Sleepers, after the infants rolled over while unrestrained, or under other circumstances,” the recall notice said.

According to the recall, consumers “should immediately stop using the product and contact Fisher-Price for a refund or voucher.”

The recall comes a week after Fisher-Price and the government agency issued a warning advising consumer to stop using the product by three months “or as soon as an infant exhibits rollover capabilities.” That warning mentioned 10 infant deaths.
