Active Newborn Sleep.

A baby’s sleep cycle begins with a drowsy phase, followed by a sleep phase known as Rapid Eye Movement (REM). They remain still and are less likely to be woken . Generally, newborns sleep about 8 to 9 hours in the daytime and about 8 hours at night. By six months, they will wake up less at night. However, this varies considerably and some babies do not sleep through the night until closer to 1 year.
About halfway through a sleep cycle, the baby falls into quiet sleep, which is characterised by slower, rhythmic breathing, less movement and no eyelid fluttering. Sleep is one of the most important parts of growth and development. While your baby has your nose or eyes, when it comes to sleep cycle, the two of you couldn't be farther apart! These cycles take around 40 minutes and are made up of both active and quiet sleep.

Anytime a newborn sleeps, it's known as a sleep cycle. This may explain why newborns don't oblige exhausted parents by lapsing into long periods of deep sleep.

Each newborn sleep cycle has both active sleep and quiet sleep, and takes about 40 minutes. REM sleep, which is characterized by rapid eye movements, is essential for learning, memory, mood, and overall health. The 10-20 minute sleep cycles were killing me. I knew he was clean and fed, and couldn’t think of what else might be causing him to keep waking up. The first thing you must know about these sleep schedules is to use the feed, wake, sleep cycle.
When a newborn awakens at the end of the sleep cycles, there is typically a quiet alert phase. During the quiet alert time, babies may look or stare at objects, and respond to sounds and motion. When a newborn awakens at the end of the sleep cycles, there is typically a quiet alert phase. We will get onto this shortly. These cycles take around 40 minutes and are made up of both active and quiet sleep. After around three months of age, the sleep pattern can be divided into ‘light sleep’ and ‘deep sleep’ cycles. They may sleep for 45 minutes, then as they transition into either passive or active, if they are hungry they’ll become fully … Infants no longer plunge directly into REM after falling asleep, and their sleep cycles begin to include longer stretches of slow-wave, "deep" sleep (Schechtman et al 1994). This is a time when the baby is very still, but awake and taking in the environment. In fact, sleep is so important that even when growth and development have been completed upon reaching adulthood, sleep–particularly REM sleep–is critical to life. This is a time when the baby is very still, but awake and taking in the environment. A baby sleep cycle lasts around 50-60 minutes. Infant sleep cycles are shorter, lasting 50 to 60 minutes, so they experience a vulnerable period for nightwaking around every hour or even less. They will often wake after active sleep phases. When a newborn wakes up at the end of the sleep cycle, there is typically a quiet alert phase. This phase usually progresses to the active alert phase. It's too risky. At this age, your baby will likely be able to start handling a bit more awake time during the day.

Most babies don’t start sleeping through the night (6 to 8 hours) until at least 3 months of age. Will my newborn sleep if I have a low milk supply?
