CPSC had previously warned consumers to use restraints in the inclined sleep products, but the reported deaths show that these devices are being used after infants learn to roll over and without restraints.
All the infants that died were 3 months or older and had already learned to roll over.
At least 10 deaths have been reported since 2015.
Fisher Price issued a product warning Friday (April 5) after receiving several reports of infants who died after rolling over in one of their products. The warning did not elaborate on what caused the infants' death.
Fisher-Price warns buyers to stop using it when infants can roll over, the commission said, but the deaths indicate some people are still using it without the restraint once their children are capable of rolling over.
"A child fatality is an unimaginable tragedy", Scothon said.
Fisher-Price has a long, proud tradition of prioritizing safety as the cornerstone of our mission.
Parents and caretakers of infants need to be careful with inclined sleepers like the Fisher Price Rock 'N Play, according to the Consumer Product Safety Commission.
The CPSC alert also urged parents and caregivers to create a safe sleep environment for infants without the use of blankets, pillows, stuffed toys or other items and to place infants on their backs to sleep.
