definition: The neonate exists in a developmental stage in which many of the adaptations of the fetus are no longer relevant to the survival demands of postnatal life. Consequently, the neonate is presented at the moment of birth with a dramatically altered set of challenges, most particularly managing to maintain physiological homeostasis outside of the mother's uterus.
