This child is not the first to fall out of the leg holes of a BB:
"INFANT CARRIERS
Kolcraft, Graco, Cosco,Evenflo and Playskool have all had hard-handle infant carriers recalled because the carriers' handles unlatched unexpectedly, often hurling infants to the ground and causing injuries that included skull fractures and concussions. Baby Bjorn, a Swedish company known for its high-end soft infant carriers, successfully resisted the CPSC's recall efforts for more than a year by claiming ignorance of Section 15: they didn't know about the CPSC's statute that requires a company to self-report product defects.
Small infants can draw up into a fetal position inside these carriers and slip out of the leg openings, 240,000 recalled. The U.S. distributor for Baby Bjorn, Regal + Lager, learned in May 1995 that a 10-day-old baby had slipped through the leg hole of a Baby Bjorn carrier and fractured his skull. Although the distributor claimed that the incident was attributable to product misuse, Baby Bjorn began manufacturing a new version of the product with smaller leg openings. A year later, a 16-day old infant fell out of her Baby Bjorn carrier and fractured her skull. Similar reports accumulated in the following months. More skull fractures, a concussion, internal bleeding were reported. All of the babies had slipped through the leg holes of the Baby Bjorn.
After several meetings involving the CPSC and Baby Bjorn's U.S. distributors, and one with Baby Bjorn's company's president, Bjorn Jakobson, an agreement was reached to recall the carrier. By the time the recall notice reached the public and the CPSC had approved the carrier "retro-fit," it was Christmas. The CPSC held the notice until January 1999, three and a half years after the first child was injured by the Baby Bjorn infant carrier."
