caption_attribution_description: English: A newborn female human infant glistens from amniotic fluid, seconds after birth, in hospital setting. Her crying demonstrates strong respiration, one of the criteria of the Apgar score used to measure the health of a child at time of birth. The head of an infant human is abnormally large in relation to the rest of the body, necessary to hold our large and developed brain. Visible in the photo is the slight deformity of the head into a "cone" shape, as a result of vaginal delivery, or childbirth. The umbilical cord has not yet been cut and still extends into the mother's body, where it connects to the placenta. The baby is the photographer's daughter. Español: Bebé humano hembra recién nacido (cuyo cuerpo brilla por el líquido amniótico que lo cubre), segundos después del nacimiento en un entorno hospitalario. Su llanto demuestra una respiración fuerte, uno de los criterios del puntaje de Apgar utilizado para medir la salud de un niño en el momento del nacimiento. La cabeza de un bebé humano es anormalmente grande en relación con el resto del cuerpo, y ello es necesario para contener nuestro cerebro grande y desarrollado. En la foto es visible la leve deformidad de la cabeza en forma de "cono", como resultado del parto vaginal. Nótese que el cordón umbilical aún no fue cortado, y que aún se encuentra extendido sobre el cuerpo de la madre, conectando con la placenta. Tiếng Việt: Một trẻ sơ sinh, vài giây sau khi lọt lòng mẹ. Chưa cắt dây rốn và nước ối còn tràn trên da của trẻ. Đứa bé là con gái của người chụp.
context_page_description: An infant is the more formal or specialised synonym for "baby", the very young offspring of a human. 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 medical contexts, newborn or neonate refers to an infant in the first 28 days after birth; the term applies to premature, full term, and postmature infants; before birth, the term "fetus" is used. The term "infant" is typically applied to young children under one year of age; however, definitions may vary and may include children up to two years of age. When a human child learns to walk, the term "toddler" may be used instead.
  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.
context_section_description: The umbilical cord of a newborn is bluish-white in color. After birth, the umbilical cord is normally cut, leaving a 1–2 inch stub. The umbilical stub will dry out, shrivel, darken, and spontaneously fall off within about 3 weeks. This will later become a belly-button after it heals. Occasionally, hospitals may apply triple dye to the umbilical stub to prevent infection, which may temporarily color the stub and surrounding skin purple.
  The umbilical cord contains three vessels: two arteries and one vein. The two arteries carry blood from the baby to the placenta while one vein  carries blood back to the baby.
