Document Summary

Maternal factors are, nutrition, disease, and emotional state of the mother have an impact on prenatal development. Infants born to girls 15 years or under. Apporximately 38 weeks after conception, contractions of the uterine muscles begin, initiating birth of the baby. Maturing lungs of the fetur may release protein triggering onset labour. Obstetric medications slow labour and may increase chance for fetal oxygen deprivation. Research on the birth process has revealed that many aspects of the birth experience have adaptive value and increase the likelihood of survival for the newborn. Pressure on the head during birth can cause the separate plates of the skull to overlap, resulting in a temporarily misshapen head.

Newborns sleep twice as much as young adults. The patterns of two different sleep states changes dramatically. Adult aversion to crying may have adaptive value.
