Newborn baby

A newborn or baby is the very young offspring of a human or other mammal. A newborn is an infant who is within hours, days, or up to a few weeks from birth. In medical contexts, newborn or neonate (from Latin, neonatus, newborn) refers to an infant in the first 28 days after birth. The term «newborn» includes premature infants, postmature infants and full term newborns. The term infant is derived from the Latin wordinfans, meaning «unable to speak» or «speechless.» It is typically applied to children between the ages of 1 month and 12 months; however, definitions vary between birth and 3 years of age «Infant» is also a legal term referring to any child under the age of legal adulthood.

A newborn’s shoulders and hips are narrow, the abdomen protrudes slightly, and the arms and legs are relatively short. In the developed world, the average birth weight of a full-term newborn is approximately 7 ½ lbs.(3.2 kg), and is typically in the range of 5.5–10 pounds (2.7–4.6 kg). The average total body length is 14–20 inches (35.6–50.8 cm), although premature newborns may be much smaller. The Apgar score is a measure of a newborn’s transition from the uterus during the first minutes after birth.
