Division of Infant Neonatal Period

Partunate period (starting at birth until between fifteen and thirty minutes after birth) 

This period began with the release of the fetus from the mother's uterus and ends after the umbilical cord is cut and tied. Until this is done, the baby is still a pascamatur, the environment outside the mother's body.

Neonate period (from the umbilical cord cutting and binding until around the end of the second week of life pascamatur) 

Now the baby is a separate individual, independent and no longer a parasite. During this period the infant must make adjustments to the new environment outside the mother's body.
