Two million Graco strollers are being recalled over child safety concerns.

Graco and the Consumer Product Safety Commission received four reports of infant strangulations that happened between 2003 and 2005.

Officials with the CPSC say if a baby isn’t strapped into the stroller, he or she can slide through the opening between the stroller tray and the bottom of the seat – where the child can get stuck and be strangled.

The recall involves older versions of the Graco Quattro Tour and the Metro Life strollers and travel systems, all made before 2007.

Consumers should immediately stop using the recalled strollers and contact Graco for a free repair kit. To order a repair kit, call Graco toll-free at (877) 828-4046 anytime, or visit the firm’s website at www.gracobaby.com.
