How baby sleep works- At 1 month, no difference between daytime sleep and nighttime sleep. Without preferences between day and night, at this age you may experience what will be a short sleeper or a long sleeper: some babies sleep 20 hours, for others 14 hours are enough. Sleep consolidates the memory and everything the child learns during the day, stimulates growth hormone secretion, strengthens the immune system, allows the body to slow down and the brain to "cleanse" itself of toxins accumulated during wakefulness.
- At 2 months, the acquisition of the circadian rhythm begins. The periods of wakefulness begin to concentrate towards the afternoon and evening, often associated with a certain restlessness linked to adaptation to extrauterine life. The child begins to acquire the circadian rhythm, organized on the periodicity of the 24 hours, the cardiac and respiratory activity and the hormonal secretions.
- At 3 months, nocturnal sleep and daytime sleep are differentiated. Sleep is reduced to 13-14 hours. The child begins to structure his sleep-wake rhythm, with longer periods of wakefulness alternating with shorter daytime naps and longer nighttime sleeps.
- At 4-6 months, nocturnal sleep Overall sleep needs remain 12-14 hours, concentrated in the night and more continuous hours. The child begins to be influenced by the light/dark alternation.
- At 7-9 months, nocturnal awakenings Nocturnal sleep is conditioned by separation anxiety and by the daily news that the child faces with energy. Nocturnal awakenings are usually concentrated between 21 and 24 and between 3 and 6; the administration of water, herbal teas, milk, or moments of play can favor the awakening of the child.
- At 10-12 months, acquisition of sleep-wake rhythm and lifestyle habits.
