Don't buy used. For safety's sake, don't use a hand-me-down or garage-sale play yard. Older models may have a top-rail hinge that can collapse, forming a steep, V-shaped angle that puts children at risk of being trapped or strangled. They may also have changing-table restraint straps that can form a loop beneath the changing table, posing a strangulation hazard to a child in the play yard. For example, in 2007 the Consumer Product Safety Commission announced a recall of 425,000 Kolcraft play yards for that reason. And in January 2009, the CPSC announced a recall of 200,000 Fisher-Price Rainforest Portable Play Yards manufactured by Simplicity Inc. and SFCA Inc. after 1,350 reports of side-rail collapse; injuries included cuts, bruises, and broken bones. In the past, incidents of side-rail collapse have resulted in more serious injuries and some deaths. Even if you plan to buy new, protect yourself by signing up for e-mail recall notices at www.cpsc.gov/cpsclist.aspx. And send in the registration card to the manufacturer to ensure that you'll be informed of any recalls. Play yards are one of the 18 types of juvenile products that must, by law, include pre-addressed, postage-paid product registration cards and an easy way to register your product online. Manufacturers are forbidden from using or sharing the information you put on those cards for marketing purposes.
Do not use the play yard once your baby has outgrown it: Stop using the play yard right from the day your baby outgrows the recommended age. You may be tempted to use it for some more days or weeks but this can be very dangerous since play yards are designed to meet the specific height and weight requirements of babies of certain age. The build materials may not be able to sustain the increased weight of a baby who has outgrown the recommended age of the playard thus posing a risk of injury.
