The children’s product company Kids II has recalled 700,000 rocking baby sleepers after the deaths of five infants who had used the rocker while unrestrained.

Kids II, which manufactures baby product for brands such as Baby Einstein, Ingenuity, Bright Starts and Disney Baby, is offering consumers a refund for their recalled baby rockers, the United States Consumer Product Safety Commission said in a statement on Friday announcing the recall.

Approximately 694,000 Kids II rocking sleepers were sold nationwide at Walmart, Target, Toys “R” Us and online from March 2012 to this month, according to the safety agency. The sleepers usually cost $40 to $80.

The recall comes weeks after Fisher Price recalled 4.7 million of its Rock ’n Play sleepers after it was reported that at least 10 infants had died of suffocation since 2015 after rolling over from their backs to their stomachs while in the seat. After first issuing a safety warning for the sleeper, Fisher Price eventually recalled the product.
