The Baby At Birth
During normal birth, the head appears first, the shoulders turn, and
more contractions push the baby out. The baby's mouth and nasal passages
are cleared of mucus, the baby breathes, cries, and is given to the
mother. When the umbilical cord ceases to pulsate, it is clamped and cut.
By the time a baby is born it already knows how to nurse, since it has
been sucking its own thumb for months.
