Fisher-Price is recalling its Rock 'n Play Sleepers after multiple reports of infant deaths.
The company said it would refund purchases for the sleepers.
The US recall covers about 4.7 million sleepers, which sold for between $US40 ($55) and $US149 ($207) since 2009.
"Fisher-Price and the CPSC knew about deaths linked to this product for years and could have taken steps to avoid this unnecessary tragedy", Consumer Reports President Marta Tellado said in the statement.
A separate Consumer Reports investigation linked the device to at least 32 infant deaths, including some for babies younger than the 3-month-old benchmark from Fisher-Price's original warning. "All other inclined sleepers should be investigated by the Consumer Product Safety Commission".
Evan Overton, the infant's mother, said they haven't filed suit but are negotiating with Fisher-Price. The Rock 'n Play Sleeper and others like it increase the risk of suffocation and strangulation. Over 30 fatalities have been reported since the product was introduced in 2009. This is due to infants rolling over while unrestrained.
The AAP does not recommend any sleeping products for infants or any products that require restraining a baby. The AAP rarely issues warnings about child products or pushes for recalls.
The parent company of Fisher-Price, Mattel, told the New York Times in a statement that parents should "always use the provided restraints, always place infants on their backs to sleep, and make sure that no pillows, blankets or extra padding are placed in the Rock 'n Play sleeper".
The AAP has warned that inclined sleepers such as these do not align with safe sleep guidelines, which state that babies should be put to bed alone on their backs, on a firm, flat mattress, free from soft bedding.
