(CNN) The Consumer Product Safety Commission is asking customers to stop using a Fisher-Price baby sleeper if their children are able to roll over because several infants have died.

The commission and Fisher-Price issued a warning Friday about the Rock 'n Play sleeper, citing reports of 10 infant deaths since 2015.

The infants, who were 3 months or older, rolled from their back to their stomach or side while unrestrained, the commission said. The warning did not elaborate on what caused the infants' death.

The latest death was reported last month, said Patty Davis, a spokeswoman with CPSC. It's unclear when the other deaths took place.

The CPSC is recommending the public to stop using the sleeper if their children are 3 months old or "as soon as an infant exhibits rollover capabilities."
