Why is your little one laughing in his sleep?

First of all, know that even adults can laugh while sleeping. If you stay up late a lot, your partner sometimes laughs while they sleep. It is not known why this happens, but there are a few theories about this condition:

Natural Reflex

If your baby laughs while sleeping, it could be a natural reflex. Your babies have known how to dream since they were still in the womb. After birth, your babies will continue to dream. Sometimes laughing during sleep is just a natural reflex in a baby’s REM cycle (Find out what REM is in the next section), especially during the active sleep phase.

While sleeping, your baby will have unconscious movements, such as smiling or waving his hands while at rest. These smiles are just thoughtful smiles, and it’s not because of emotion or interest in something.

A child safety feature

Many people, including experts, believe that your baby’s smiles are a type of safety feature that makes your newborns more attractive, adorable, and cute. It is as if you have a sexy body; your baby has a smile to attract people.

And those smiles will keep them safe and prevent them from being abandoned. Even if you are angry, you can throw it away when your toddler is smiling at you. And the moment your sweetheart smiles while sleeping is adorable, too.

These features are accompanied by many other characteristics of infants including big eyes, smooth skin, cute expression, etc. Everything about your baby can activate and take care of your unconditional love instincts.

Your child processes information

During the first months of life, babies go through a continuous learning process. They start by learning to open their eyes, to smile, to cry, to find ways to move parts of their body. There is always so much news for your little one. Therefore, the baby still has to process new information.

In addition, from birth, your baby must interact with light and sound in a different setting. They also face so many different objects with different shapes, colors and sizes. And this thing will make your babies feel overwhelmed.

Therefore, it is only at bedtime that babies have time to process this large amount of information and express it by crying or laughing. You may believe that when you sleep and smile your baby is expressing a lot of the emotions that he has learned.

The sleep cycle of a newborn baby

Each cycle of your baby’s sleep will last approximately 90 minutes, consisting of five stages. The first four stages are non-rapid eye movements (NREM). In the fifth stage, new eyes move rapidly (REM). And below, precise information on each step:

Step 1

This stage is when your baby begins to fall asleep, so it is “relatively shallow sleep”. This stage lasts a short time, just a few minutes after your baby has fallen asleep. When breathing slows down, your baby’s muscles start to relax and brain waves slow down.

2nd step

This stage represents approximately 50% of the time of sleep. At this point, you can barely find movement in your children’s eyes. And also, at this stage, the brain activity becomes slower than the previous stage.

Steps 3 and 4

At this point, your babies have fallen into a deep sleep. The body is completely rested. In addition, the baby’s temperature, heart rate, respiratory rate and even blood pressure are all reduced to the lowest level. At this time, the brain waves are also slowed down.

Step 5

REM sleep typically occurs 1.5 to 2 hours in healthy sleep. When your sleep reaches the REM stage, your eyes move quickly, still having dreams. At this time, the baby’s breathing is irregular; the baby’s heart rate and blood pressure will be the same when awake.

However, your body is temporarily paralyzed so that your babies do not act like what they saw in the dream. This is why you often see your baby cry, laugh, and even jump while he sleeps.

Baby smiles while sleeping

Laughter during sleep often happens when your baby is in the REM stage, but that doesn’t mean it doesn’t happen in the early stages. Additionally, laughing while sleeping can sometimes be due to insomnia or a sleep disorder. Some babies will have this condition of a newborn baby.

Compared to adults, a baby’s REM sleep is typically shorter and only lasts 30 to 50 minutes. The length of this sleep phase will increase as your baby grows.

The meaning of your baby’s smile

There are a few answers to your question of “why do babies smile while they sleep,” including emotions, the REM cycle, and more. But do you know that your baby has a different type of smile with different meanings? Researchers have divided your baby’s smile into three groups: reflective, responsive, and social.

Reflexive smiles

As mentioned, reflex smiles often occur in infants. You will see your baby smile before the age of six weeks. At this point, your baby’s body goes through physiological changes to activate and develop certain reflexes, and smiling is one of them. These smiles are a natural way for your baby to learn and practice different skills.

Responsive smiles

Warm smiles often appear when your baby is between six and eight weeks old. It’s time for your little one to smile to react with the environment since he can see and recognize something. It is only the emotional response but not a social response.

Social smiles

At 3 to 4 months, your baby wants to connect with the world. He may recognize that mom and dad are the primary caregivers, so he’ll smile when he sees you. Plus, your baby will laugh when you make unusual noises, faces, cuckoos and more.

Baby dreams too

Babies dream more than adults. Before six months, babies typically imagine more than half of their time asleep. And as mentioned, they even dream since they are still in the womb. Dreams often help your little one understand their experiences.

Therefore, right from the womb, when your baby will only be able to listen and smell, he will dream of amniotic fluid and try to get to know it. This process will continue for the first few months.

After birth, even if your child still cannot tell you what your child is dreaming of, there are some clues you can still rely on to decipher your baby’s dream. In particular, the most significant evidence that mothers need to pay attention to is their babies’ behavior during sleep and upon waking.

If your baby smiles while he sleeps and after waking up, he may have had good dreams. If your baby is getting cranky and crying, it’s likely he or she had a bad idea. Although bad dreams often occur later, your baby may develop feelings of fear from a young age.

What should the parent react to the baby’s laughter?

You won’t see it very often. But sometimes your babies have fits that lead to uncontrollable laughter. Parents should therefore check carefully. The symptom of seizures is that your baby can laugh continuously within 10 to 20 seconds. And this often when the children are ten months old. If this symptom occurs often, take it to the pediatrician.

In addition, you should not wake your baby up when he is sleeping even if he is smiling or crying as this can disrupt your baby’s sleep and make him angry.

Every child is different. So keep in mind that some infants and toddlers can fall asleep very quickly. In contrast, others sleep less soundly for about 20 minutes before falling asleep. So parents, don’t worry if your babies are laughing or not laughing while they sleep. It is based on the phase of sleep.

Final words

When you have a child, it is not only your baby who has weird emotions, but even mom also feels very weird. And as your baby learns to open his eyes, cry, laugh, move his body and the world around him, you need to learn your baby.

Parents need to get used to your little one’s routine, habits and expressions. However, if you find your baby laughing while she sleeps, don’t stress yourself out by continuing to ask “why do babies laugh for no reason.” It is a natural process that your baby must go through in order to develop fully.
