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 have a base made of hard plastic sitting on top of wheels and a suspended fabric seat with two leg holes. A baby walker often has toys attached to the top to entertain the baby. It is designed for a child between 4 and 16 months of age. Baby walkers were known as early as the 1440s in Europe. An illumination in the Hours of Catherine of Cleves, a Dutch manuscript from that time, depicts the infant Jesus in a wooden baby walker. ==Safety issues== Many parents believe that such walkers teach a child to walk faster; however, studies suggest that it is not true, and they may actually delay walking by two to three weeks. These devices have also led to many injuries. In fact, CPSC, American Academy of Pediatrics, Kids In Danger, and other organizations〔(Kids In Danger )〕 have issued warnings to discourage parents from using baby walkers. In Canada, the sale of baby walkers was banned on April 7, 2004.〔(【引用サイトリンク】url = http://news.bbc.co.uk/2/hi/americas/3609723.stm )〕 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 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 $100,000 or sentenced to up to six months in jail.〔 /〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「baby walker」の詳細全文を読む スポンサード リンク
