Hundreds of thousands of Fisher-Price 4-in-1 Rock 'n Glide Soothers and 2-in-1 Soothe 'n Play Gliders sold in the United States and Canada have been recalled after four U.S. infants died of suffocation.

The deaths occurred in the 4-in-1 Rock 'n Glide Soothers. The infants were placed on their backs unrestrained in the product and were later found on their stomachs, according to the U.S. Consumer Product Safety Commission (CPSC). These incidents occurred between April 2019 and February 2020 and involved a 4-month-old from Missouri, a 2-month-old from Nevada, a 2-month-old from Michigan, and an 11-week-old from Colorado. No deaths have occurred in the 2-in-1 Soothe 'n Play Gliders, the CPSC said.

"These types of incidents are heart-breaking," Robert Adler, acting chair of the CPSC, said in an agency news release. "Loving parents put their babies in these products never expecting a tragedy. Inclined products, such as gliders, soothers, rockers and swings are not safe for infant sleep, due to the risk of suffocation."

About 120,000 4-in-1 Rock 'n Glide Soothers and 55,000 2-in-1 Soothe 'n Play Gliders were sold in the United States from January 2014 through December 2020, and about 55,000 2-in-1 Soothe 'n Play Gliders were sold from November 2018 through May 2021. About 25,000 4-in-1 Rock 'n Glide Soothers and 27,000 2-in-1 Soothe 'n Play Gliders were sold in Canada.

Consumers should immediately stop using the recalled products and contact Fisher-Price for a refund, CPSC said. This can be done by going to the Fisher-Price website and clicking on Recall & Safety Alerts, or by calling toll-free at 855-853-6224 from 9 a.m. to 6 p.m. ET Monday through Friday.
