Toymaker Fisher-Price has recalled nearly five million of its Rock 'n Play sleepers after reports linked the product to dozens of baby deaths.
The recall was announced on Friday by the US Consumer Product Safety Commission (CPSC).
On its website, the commission said at least 30 infants had died in the sleeper model since its 2009 release.
Fisher-Price owner Mattel confirmed the voluntary recall but stood by the product's safety.
The CPSC said that it was aware of 10 infant deaths in the Rock 'n Play that occurred when infants rolled from their back onto their stomach or side while unrestrained.
All of the 10 infants were at least three months old.
Fisher-Price had warned customers to stop using the sleeper once infants can roll over.
The CPSC has estimated the recall affects about 4.7 million products.
