With the perspective of describing some aspects of the ontogenesis and organization of the sleep stages during the first year of life, a literature review was carried out to assess the physiological and behavioral alterations controlled by changes occurring during sleep at this developmental stage. In addition, based on the sleep preceding theory, the stages of differentiation, classification and time organization of sleep stages are presented, aiming at the favorable management of environmental events that affect the organization of infant sleep.
