Subtopic: Normal infant sleep
– In the first week of life, infants sleep during both day and night, waking to feed every 2-4 hours.
– Over the first two weeks, infants average 16-18 hours of sleep daily without a set circadian rhythm.
– By around 2 months, a day-night pattern slowly emerges.
– At 3 months, sleep cycles may increase to 3-6 hours, with most infants still waking at night to feed.
– By 8 months, most infants wake at night but can self-soothe back to sleep.

Subtopic: Infant sleep patterns
– Infant sleep can be categorized into active sleep (AS) and quiet sleep (QS).
– Active sleep is similar to adult REM sleep, characterized by eye and body movement.
– Infants spend about half their sleep time in AS/REM and half in QS, unlike adults.
– By 3 months, infants start to enter quiet sleep at the beginning of their sleep cycle.
– Sleep cycle duration starts to resemble adult sleep more around 6 months.

Subtopic: Vulnerability during sleep
– Infants are susceptible to suffocation and SIDS during sleep.
– Safe sleep practices are crucial to reduce risks during infant sleep.
– Historically, infants slept with parents on the ground, but modern practices vary.
– Infants should not sleep with pillows or blankets to prevent suffocation.
– Infants frequently sleep in various types of beds or share a bed with parents.

Subtopic: Infant sleep disturbances
– Infant sleep disturbances are common and can disrupt parental sleep.
– Daytime napping typically continues until 3-5 years of age.
– Infants may experience frequent night waking, which is considered adaptive.
– Frequent night awakenings are protective against SIDS.
– Infants may wake during the night even at 9 months of age.

Infant sleep (Wikipedia)

Infant sleep is an act of sleeping by an infant or a newborn. It differs significantly from sleep during adulthood. Unlike in adults, sleep early in infancy initially does not follow a circadian rhythm. Infant sleep also appears to have two main modes - active, associated with movement, and quiet, associated with stillness - exhibiting distinct neurological firing patterns. Sleep duration is also shorter. As the infant ages, sleep begins to follow a Circadian rhythm and sleep duration increases. Infants nap frequently. Infants are also particularly vulnerable during sleep; they are prone to suffocation and SIDS. As a result, "safe" sleep techniques have been the subject of several public health campaigns. Infant sleep practices vary widely between cultures and over history; historically infants would sleep on the ground with their parents. In many modern cultures, infants sleep in a variety of types of infant beds or share a bed with parents. Infant sleep disturbance is common, and even normal infant sleep patterns can cause considerable disruption to parents' sleep.
