Document Summary
Child development chapter 2 (end): prenatal development and the newborn period. * a state of arousal refers to a continuum of arousal ranging from deep sleep to intensive activity. * on average newborns sleep twice as much as young adults do and decreases from there. * patterns of rem (active sleep, quick eye movements, distinctive pattern of brain activity, body movements, irregular breathing) and non-rem sleep (quiet, deep sleep, lack of motor activity) change over time as well; Rem sleep constitutes 50% of an infants sleep which may be to make up for the deprivation of visual stimulation that infants may experience. * newborns tend to sleep more at night than during the day, and when the child begins sleeping fully through the night depends on culture and how much their parents encourage it. * the combination of holding, rocking and talking or singing is most effective rather than just one.
