What are the stages of sleep of babies? The dream of human beings is the subject of great research. What happens since we close our eyes at night until we open them the next morning is an enigma that little by little we can discover.
When we sleep, we all go through different stages of sleep. But the stage of sleep of babies is not the same as those of an adult. It is very interesting for parents to know how sleep works in babies to better understand their sleeping patterns.
Stages Of Sleep Of Babies
An adult goes through 5 phases of sleep, 4 subphases of non-REM sleep (non-rapid eye movement) divided into a light sleep and deep sleep, and an REM phase (rapid eye movement), a very light type of sleep.
Instead, the baby’s sleep pattern is very different. A newborn baby has only two of the five phases. They are deep sleep and the REM phase.
The ‘why’ is very simple. A newborn needs to wake up several times to eat. If he had five phases, he would need much more time to sleep and could not feed himself as many times as he has to. They spend more time in REM sleep. Then, babies enter a phase of deep sleep (not REM) from which they can easily wake up. Every night alternates both phases.
Perhaps there is the key to many misunderstandings. It is absolutely natural and normal for a baby to wake up at night. He does it so that “someone”, usually his mother, satisfies his need to eat. That’s why babies wake up crying. It is his way of calling mom to feed him or simply to hug him in her arms, which, like eating, is a basic need of the newborn.
Understanding this is essential to understand why it is not healthy to try to modify the stages of sleep of babies. Indeed, it goes against their own nature.
When Do We See Changes On Babies?
The stages of sleep of babies change around six months (age) when the baby acquires the rest of the phases. But like everything, it takes time to learn to “use them.” A period of adaptation begins in which the child is practicing ‘how to sleep’. There will be nights that he wakes up many times, others less and maybe some, around half a year old, he will be able to sleep all night.
As parents, we have to accompany them and comfort them in their interrupted nights to make them feel safe.
