Along the days following birth, a series of emotional manifestations emerge between the baby and the people around him, especially the parents. Like all people, adults or children, the newborn has a sleep-wake cycle during the day. The newborn’s cycle is shorter than that of the adult and is repeated between 6 and 8 times in the first days. Its duration is between 3 and 4 hours. The length of the sleep period is variable ranging from 2 and a half hours to 4 to 5 hours. In the first weeks the newborn sleeps 16 to 17 hours a day. Awake periods last an average of two hours. Around the first month and a half they sleep more at night than during the day. The time of this cycle increases in during the following months due to decreased sleep periods and increased wakefulness. There are a series of important stages that must be known during wakefulness because they generate strong bases for the development of parents and children. They were described by Lier.
