Fisher-Price has decided to recall the popular Rock ‘n Play Sleepers.

Over 30 infant fatalities have occurred in Rock ‘n Play Sleepers since the product was introduced in 2009 according to The U.S. Consumer Product Safety Commission.

The CPSC says the deaths happened after "the infants rolled over while unrestrained, or under other circumstances." There are over 4.7 million Rock ‘n Play Sleepers in the United States.

Rock ‘n Play Sleepers were sold all over the United States from $40 to $149. Anyone with one of these are directed to contact Fisher-Price online at www.service.mattel.com and click on “Recalls & Safety Alerts” or at 866-812-6518 from 9 a.m. to 6 p.m. ET Monday through Friday for more information.
