Women Are Encouraged to Nurse Their Babies as Soon as Possible

Women are encouraged to nurse their babies as soon as possible after giving birth because

A) prolactin released in response to a baby's suckling promotes the mother-child bond.
B) oxytocin released in response to a baby's suckling augments uterine contractions, which helps to reduce the size of the uterus and stop bleeding.
C) such contact prompts the release of pain-reducing chemicals by the brain.
D) the absence of a baby's crying stimulates greater release of oxytocin.
E) the infant needs immediate nutrition, since it can no longer rely on the placenta.
