The child is born after a pregnancy period of approximately nine months. 

During childbirth, the muscles of the mother's womb begin to contract and the amniotic fluid is released. The child is released from the mother's body through the vagina. It arrives into the world head first.

After this, the child's umbilical cord is cut. The child begins breathing with its own lungs. 

The mother breastfeeds the child for several months. The mother's milk contains plenty of energy and important substances, which the child uses to grow. 

A young baby is completely dependent on other people. This is why a baby needs large amounts of protection and affection.
