The AAP, meanwhile, said it doesn't recommend children using "inclined sleep products like the Rock 'n Play, or any other products for sleep that require restraining a baby".
The toy and infant-care company said all consumers should immediately stop using the sleepers, of which about 4.7 million have been made.
TODAY'S TMJ4 reached out to the Consumer Product Safety Commission on Friday, asking why the voluntary recall was decided.
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.
"This product is deadly and should be recalled immediately", Dr. Kyle Yasuda, the head president of the AAP, said in a press release.
Contact Fisher-Price online at www.service.mattel.com and click on "Recalls & Safety Alerts" or at 866-812-6518 from 9 a.m.to 6 p.m. ET Monday through Friday for more information. The report came following a CPSC warning last week that tied 10 fatalities to the rockers.
"With these actions, we want parents around the world to know that safety will always be a cornerstone of our mission, that we are committed to these values, and will continue to prioritize the health, safety and well-being of the infants and preschoolers who utilize our products", Scothon said.
In addition, the American Academy of Pediatrics recently urged the CPSC to order a recall on the Rock 'n Play immediately, claiming that its April 5 statement "did not go far enough to ensure safety and protect infants". The product was manufactured in China.
"When parents purchase a product for their baby or child, many assume that if it's being sold in a store, it must be safe to use".
