How many months does the baby know how to make people laugh?

Babies are very smart. A small action of mom and dad can affect their emotions. After a few months, the baby will know that mom and dad are joking with him, and he will laugh happily and interact with mom and dad. If parents are too busy, they may neglect to spend time with their children, which will lead to their children becoming too withdrawn. So, at what age can babies learn to be amused?

Generally speaking, babies can laugh out loud at around three months old.

First month:

1. In the first month after birth, even when the baby is sleeping, you can see his eyelids twitching occasionally and a fleeting smile.

2. Those smiles in sleep are fleeting, and if parents are not paying attention, even such smiles cannot be seen.

1-2 months:

1. A true smile comes from happiness.

Generally, at 6-8 weeks old, babies begin to smile even when awake, and this smile is different from the unconscious smile before.

2. This time he is responding to happy things, such as when you touch his little face with your hand, or hold him and hum a lullaby, he will give you a big smile in return.

2-3 months:

The most beautiful smile is shown to you

At about 12 weeks old, your baby displays his or her social smile, and you'll be delighted that this most beautiful smile is directed at you.

This kind of smile is often called a mouth smile by psychologists. Some studies even suggest that babies will have smile-like facial movements within 2 to 12 hours after birth. This smile usually occurs when the baby is sleeping or sleepy. It appears suddenly and is extremely subtle, even difficult to detect.

The most obvious manifestations are: raising the corners of the mouth and moving the muscles around the mouth.

1. When his physiological needs are met, for example, when he is full and has enough to drink, and in a warm environment with soft sunshine and gentle and pleasant music, he will laugh spontaneously to express the satisfaction of his physiological and psychological needs.

2. The smile at this stage is caused by environmental or internal reasons, whether it is because the baby feels comfortable, or because of music or physical touch. It is related to the spontaneous subcutaneous discharge of the baby's cerebral cortex. But it has no real social significance.

Babies will instinctively smile when they are awake, full, or hear soft music.

At 3 weeks of age:

When babies are awake and their bodies are touched by their parents, they will naturally smile.

4 to 5 weeks old:

Babies can also smile when they hear familiar sounds or clap their hands.
