The term may also be used to refer to juveniles of other organisms. A newborn is, in colloquial use, an infant who is only hours, days, or up to one month old. In British English, an infant school is for children aged between four and seven. As a legal term, “infancy” continues from birth until age 18. A newborn’s shoulders and hips are wide, the abdomen protrudes slightly, and the arms and legs are relatively long with respect to the rest of their body. In first world nations, the average total body length of newborns are 35.
In developed countries, the average birth weight of a full-term newborn is approximately 3. A newborn’s head is very large in proportion to the body, and the cranium is enormous relative to his or her face. During labour and birth, the infant’s skull changes shape to fit through the birth canal, sometimes causing the child to be born with a misshapen or elongated head. It will usually return to normal on its own within a few days or weeks. Special exercises sometimes advised by physicians may assist the process. Some newborns have a fine, downy body hair called lanugo. It may be particularly noticeable on the back, shoulders, forehead, ears and face of premature infants.
Lanugo disappears within a few weeks. Immediately after birth, a newborn’s skin is often grayish to dusky blue in color. As soon as the newborn begins to breathe, usually within a minute or two, the skin’s color reaches its normal tone. A newborn’s genitals are enlarged and reddened, with male infants having an unusually large scrotum. The breasts may also be enlarged, even in male infants.
