More than 2 million MamaRoo swings and 220,000 RockaRoo rockers are being recalled after a 10-month-old died as a result of getting caught in a strap, according to the U.S. Consumer Product Safety Commission in an announcement Monday.

According to the CPSC, the Mamaroo recall was initiated because “when the swing or rocker is not in the use, their restraint straps can hang below the seat and non-occupant crawling infants can become entangled in the straps, posing entanglement and strangulation hazards.”

4moms, the Pittsburgh, Pennsylvania-based company behind the MamaRoo and RockaRoo, has received two reports of entanglement incidents involving infants who became caught in the strap under the unoccupied MamaRoo infant swing after they crawled under the seat.

In addition to the 10-month-old infant who died from asphyxiation, another 10-month-old infant suffered bruising to the neck from the restraint straps of the MamaRoo before being rescued by a caregiver.

The MamaRoo is an incredibly popular baby swing that offers multiple motions and speeds. Buttons on the base control the motion, speed and sound—the swing’s motion is often compared to the motion of a mom when she holds her baby.

If you own a MamaRoo swing or RockaRoo rocker and are concerned about the recall, here’s what you need to do:

Check the model number located on the bottom of the unit. This MamaRoo recall includes only MamaRoo models that use a 3-point harness. (The MamaRoo model that uses a 5-point harness is not included in this recall.)

  • Versions 1.0 and 2.0 (model number 4M-005)
  • Version 3.0 (model number 1026)
  • Version 4.0 (model number 1037)

The RockaRoo model number is located on the bottom of the unit: 4M-012 is the model involved in the current recall.

4Moms recommends that consumers with infants who can crawl immediately stop using the recalled swings and rockers and place them in an area where crawling infants cannot access. If you own one of the affected models, you should contact 4moms immediately to register for a free strap fastener that will prevent the straps from extending under the swing when not in use.
