A baby walker is a device that can be used by infants who cannot walk on their own to move from one place to another. Modern baby walkers are also for toddlers. They have a base made of hard plastic sitting on top of wheels and a suspended fabric seat with two leg holes. In the US, baby walkers are responsible for about 2000 injuries annually to children serious enough to require a trip to the emergency room, prompting calls from pediatricians for their outright ban. Cause of developmental delays Many parents believe that such walkers teach a child to walk faster. However, they may actually delay walking by two to three weeks for a typical child. The amount of use matters; for every 24 hours babies spend in a baby walker (for example, one hour per day for 24 days), they learn to walk three days later and to stand four days later than they would have. Safety issues Baby walkers have also led to many preventable injuries caused by tripping, toppling over, or skidding on wet floors. These include injuries from falling down stairs while moving around in the baby walker, often with injuries that are worse than typical for falling down the stairs. Walkers allow babies to reach areas they otherwise couldn't, including pools, bathtubs, and kitchens, where they can be at risk for burns from pulling boiling food off stovetops. The total number of baby walker-related injuries is likely an underestimation because there are more than 40 different terms used in academic or news reports for these devices, thus complicating a tally of the number of device-related injuries. The U.S. Consumer Product Safety Commission, American Academy of Pediatrics, Kids In Danger, and other organizations have issued warnings to discourage parents from using baby walkers. Direct education of parents in a medical setting reduces parents' willingness to use these devices. In Canada, the sale of baby walkers was banned on April 7, 2004. Canada is the first country in the world to ban the sale, importation and advertisement of baby walkers. This ban extends to modified and second hand baby walkers, including those sold at a yard sales or flea markets. The Canadian Consumers Product Safety Improvement Act of 2008 (CPSIA) changed the items that were allowed to be sold at such sales. Owners of baby walkers may be fined up to CA $100,000 or sentenced to
