Various methods of baby transport have been used across different cultures and periods and for different ages of children. Methods can be divided between wheeled devices including baby carriages (carrycots in British English), strollers (pushchairs), slings, backpacks, baskets, infant car seats, and bicycle carriers. The larger and heavier perambulators or prams, which had become popular during the Victorian era, were replaced by lighter and more flexible designs during the latter half of the 1900s. ==Baskets, slings and backpacks== Infant carrying likely emerged early in human evolution as the emergence of bipedalism would have necessitated some means of carrying babies who could no longer cling to their mothers and/or simply sit on top of their mother's back. On-the-body carriers are designed in various forms such as baby sling, backpack carriers, and soft front or hip carriers, with varying materials and degrees of rigidity, decoration, support and confinement of the child. Slings, soft front carriers, and "baby carriages" are typically used for infants who lack the ability to sit or to hold their head up. Frame backpack carriers (a modification of the frame backpack), hip carriers, slings, ''mei tai''s and a variety of other soft carriers are used for older children. Images of children being carried in slings can be seen in Egyptian artwork dating back to the time of the Pharaohs, and have been used in many indigenous cultures. A cradleboard is a Native American baby carrier used to keep babies secure and comfortable and at the same time allowing the mothers freedom to work and travel.〔(Cradleboard ) Encarta. Retrieved 27 March 2009. (Archived ) 2009-10-31.〕 The cradleboards were attached to the mother’s back straps from the shoulder or the head. For travel, cradleboards could be hung on a saddle or travois. Ethnographic tradition indicates that it was common practice to cradleboard newborn children until they were able to walk,〔(), Native American Cradles exhibited at Pequot Museum, The Day - October 6 2001, Retrieved 4 May 2015.〕 although many mothers continued to swaddle their children well past the first birthday. Bound and wrapped on a cradleboard, a baby can feel safe and secure. Soft materials such as lichens, moss and shredded bark were used for cushioning and diapers. Cradleboards were either cut from flat pieces of wood or woven from flexible twigs like willow and hazel, and cushioned with soft, absorbent materials. The design of most cradleboards is a flat surface with the child wrapped tightly to it. It is usually only able to move its head. On-the-body baby carrying started being known in western countries in the 1960s, with the advent of the structured soft pack in the mid-1960s. Around the same time, the frame backpack quickly became a popular way to carry older babies and toddlers. In the early 1970s, the wrap was reintroduced in Germany. In 1986, the ring sling was invented and popularized. In the early 1990s, the modern pouch carrier was created in Hawaii. While the Chinese ''mei tai'' has been around in one form or another for centuries, it did not become popular in the west until it was modernized with padding and other adjustments. It first became popular and well known in mid-2003. Portable cradles,including cradleboards, baskets, and bassinets, have been used by many cultures to carry young infants. The modern infant car seat is a relative latecomer. 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 transport」の詳細全文を読む スポンサード リンク
