The regulator said consumers should immediately stop using the product and contact Fisher-Price for a refund or voucher.

"We stand by the safety of our products. However, due to reported incidents in which the product was used contrary to the safety warnings and instructions, we have decided to conduct a voluntary recall of the Rock 'n Play Sleeper in partnership with the Consumer Product Safety Commission," Fisher Price-owner Mattel Inc said.
