Why do babies laugh when they sleep? Is it because they are dreaming when they laugh when they sleep?

When babies sleep with a smile or laugh, mothers find it very fresh. So why do babies laugh when they sleep? Is the baby dreaming when he laughs when he sleeps? Let's take a look at what babies think when they sleep~

Why do babies smile when they sleep?

1. Sleep cycle

Why do babies smile when they sleep? This is because the baby's brain is not fully developed, so the sleep cycle has deep sleep and light sleep. After a period of time, the child will wake up automatically and enter a light sleep state. Various expressions will appear on the baby's face, and sometimes even make sounds. This light sleep method is very good for the baby, because the baby can still carry out thinking activities during light sleep.

Dreaming during shallow sleep can provide images for the baby's brain development. This internal stimulation enhances the baby's brain development.

Baby's sleep state includes: deep sleep and light sleep

The baby's shallow sleep can meet the baby's physical growth needs. For example, if the baby is hungry, he will automatically wake up and cry for milk; if he is cold, he will cry and wake up his mother; if his nose is blocked and breathing is not smooth, he will easily wake up and tell his mother in a unique way.

If the baby is in a deep sleep all night, these physiological needs cannot be met, which is not good for the growth and development of the body. About half of the newborn baby's sleep is shallow, accompanied by sucking movements, and there are many facial expressions, sometimes making faces, sometimes smiling, sometimes pouting, and eyeballs moving. The limbs are often accompanied by dance-like movements. These behaviors during shallow sleep do not mean that the child is uncomfortable, so mothers don't need to worry. As the baby grows, shallow sleep decreases. During deep sleep, the baby rarely moves, is calm and peaceful, does not move his eyes, breathes regularly, and has no expression on his face.

2. Dreaming

If your baby is too excited and happy during the day, he may dream at night and laugh in his sleep. This is an unconscious laugh.

What does baby dreaming have to do with

Babies spend most of their time sleeping during this period. Adults dream during REM sleep, while babies spend 50% of their sleep time doing REM, which is twice as much as adults. But the dreams babies have are basically related to their brain activity.

When will the baby smile?

The baby's social smile will appear when he is 6 weeks old, and it will become common at 12 weeks. When the baby is 6 months old, he will often smile at familiar people. If the baby still can't smile at 3 months old, parents should consult a pediatrician. Because most babies at this age will smile at familiar and favorite people or toys.

Several ways to make children laugh

① You can go to a local baby store to buy some rattles and small toys. Wait for about 10 minutes after the baby has finished feeding. The chances of making the baby laugh are higher.

②You can also do "baby gymnastics" for your baby. You don't need to learn this kind of exercise. Just call out 1234.2234.3234 and raise your baby's hands and legs. Let him know that you are teasing him. Of course he will laugh.

③You can learn some ventriloquism on the Internet and learn how to call your child something that sounds strange, and he will naturally laugh.

④ You can play some music for your child to make him feel novel and he will laugh. (Never play rock music!)

The above points are all about teasing your baby when he is full of curiosity about the world after feeding. Never tease your baby when he is in a bad mood. That will not have any effect and will only annoy the baby, and he will cry.
