Why doesn't a newborn baby cry?

I believe that many new parents, although they are first-time parents, have relatives and friends who have given birth to babies before, so they naturally know a thing or two about taking care of babies and their habits. They will find that many children always cry and make a fuss in the early days after they are born, and are particularly naughty. They always think that their babies will be like this too, but on the contrary, their babies do not show this behavior. Why don’t newborn babies cry?

Choleric: The baby is easily excited and enthusiastic

Choleric people generally have bad tempers, are enthusiastic and cheerful, strong and straightforward, and decisive, but they are often easily excited and lack self-control. Generally speaking, choleric people are mostly passionate and impatient.

Sanguine: The baby is lively, cute, smart and clever

Most sanguine people are quick-witted, intelligent, cheerful, have broad interests, and can quickly like new things, but their interests are not stable enough and their attention is easily distracted. People with sanguine temperament give people the impression of being smart, enthusiastic, lively and active.

Phlegmatic: Babies like quiet, calm and steady

People with phlegmatic temperament are not easily excited, often appear calm, do not lose their temper easily, do not like to socialize, and do not easily have strong emotions towards others. This type of person reacts slowly and acts slowly, but is calm, steady, and down-to-earth, and can maintain mental balance no matter how the environment changes.

Melancholic temperament: The baby is very careful and sentimental

Melancholic people appear gentle and quiet; they like to be alone and are unwilling to interact with others. They often appear coy, shy, indecisive, and hesitant. However, melancholic people are more sensitive, with sharp thoughts and meticulous observations.
