This week, Kolcraft recalled one million play yards because the side rail can unlatch unexpectedly, posing a fall hazard to children. Kolcraft has received 347 reports of  play yard sides collapsing, resulting in 21 injuries to young children, including bumps, scrapes, bruises and one concussion, the Consumer Product Safety Commission reported.

The recall involves more than 20 models, including the Travelin’ Tot series sold under a number of brand names. In addition to Kolcraft, the play yards were manufactured for Carter’s, Sesame Street, Jeep, Contours, Care Bare and Eric Carle (check the recall notice for model numbers). Some of the units have a bassinet and/or changing table. Some models have a mobile, vibrating unit or a parent organizer. The model numbers can be found on a white sticker on one of the feet of the play yard.
