My baby smiles when sleeping, what's going on?

Everyone has joy, anger, sorrow, and happiness. This is also true for newborn babies. Don't think that babies only know how to cry. Some mothers will find that their babies laugh when they sleep. What is going on? Is the baby having a sweet dream? Today, the editor will talk to you about why babies laugh when they sleep.

A baby's sleep is divided into deep sleep and light sleep. Newborns sleep lightly for about half of their life, and this amount decreases as they grow. During deep sleep, the baby rarely moves, is calm and peaceful, has no eye movement, has regular breathing, and has no expression on his face. Light sleep is accompanied by sucking movements and many facial expressions, sometimes seeming to be making faces, sometimes smiling, sometimes pouting, and the eyeballs will move. The limbs are often accompanied by dance-like movements. Certain behaviors during light sleep do not mean that the child is unwell, so mothers do not need to worry.

Your baby's first smiles can be seen during sleep and drowsiness, but are rarely seen when the baby is awake or alert with his eyes open. These smiles are usually fleeting and seem to have nothing to do with the outside world. Some people call them "endogenous smiles." In fact, they are spontaneous rhythmic reactions in the baby's body, and the baby is unconscious. As the baby grows up, exogenous smiles will gradually appear. For example, when the baby sees a favorite face or hears a favorite voice, the smile that begins at this time becomes a social smile, and the baby is smiling consciously.

There is scientific evidence that babies are already dreaming in the womb. This is also proof of the baby's brain development. The baby has his own joys, sorrows, anger and happiness. When he dreams of something he thinks is funny, he will laugh, and sometimes cry. All babies who are developing healthily will experience the phenomenon of laughing in their dreams to some extent.

The above is what I want to introduce to you today about babies laughing while sleeping. You can take a look at it. I hope my sharing will be helpful to you. There is a saying among the people: the baby is smiling because the Goddess of Childbirth is making him laugh. These are all superstitious sayings, but this situation is also normal and mothers don’t need to worry.
