The U.S. Consumer Product Safety Commission (CPSC) has issued a final rule, effective  September 29, 2014, adopting a voluntary industry standard for soft infant and  toddler carriers. 

Defining such carriers as wearable, fabric products designed to carry a full-term  infant or toddler upright and close to the caregiver, the agency notes that the new  standard addresses several falling-related and other safety hazards associated with  the products, including fastener problems, large leg openings, stitching and seam  problems, and slippery straps. Between September 11, 2012, and July 15, 2013, the  agency received 31 infant-carrier related incident reports, including two fatalities.  See Federal Register, March 28, 2014.
