About 4.7 million Fisher-Price Rock-Play sleepers are recalled after a federal commission linked the product to more than 30 infant deaths.

The commission said Friday that "more than 30 children have died in Rock 'n Play Sleepers, after the kids have returned without restraint or in other circumstances" since 2009.

The CPSC said it had previously warned consumers to use restraints in slanted baby products.

Fisher-Price says its bed complies with all safety standards and reminded parents to use restraints, put babies on their backs to sleep, and make sure that they're safe. no blanket or pillow is placed in the bed.
