How does the baby breathe?
There is a complex physiological mechanism which inhibits the baby from taking a breath when it is born in water. It is commonly believed that the stimulus to breathe is from the baby’s face coming in direct contact with air. Up until the time that the baby is lifted out of the water, the baby receives its oxygen from the mother via the placenta and the umbilical cord.
