Some people say that babies who laugh earlier are smarter, is it true or false?

It is true, because such infants and young children develop early, their development is also very mature, filial piety is a positive value for the baby's brain development, and helps to promote the baby's intellectual development.

After many babies are born, their reaction ability will be relatively fast, and they will have obvious feelings about the teasing of adults.

This statement must be reliable, because the development of brain nerves can better control the expression of his face, which shows that his brain is very responsive, and can also better express his emotions through eye contact with his mother, which is a very smart performance.

This statement is not reliable, each child grows and develops differently, some babies will laugh at birth, but it does not mean that the IQ is high, many times, IQ also needs to be cultivated

I don't think this is a reliable claim, and there is no scientific evidence to prove that children who laugh earlier are smarter.

It's also a little reliable, because crying is a baby's instinctive reaction, but laughing is different, he learns it the day after tomorrow, so the sooner the baby learns to laugh, the smarter it will be, and there is no problem with this statement.

Unreliable, the degree of intelligence is not determined by this statement, it is determined by the later cultivation and children's comprehension ability.

This statement is unreliable, and the baby who can laugh can only say that the child loves to laugh more, but it has nothing to do with being smart.

Unreliable. Because there is no scientific basis for this statement, and there is no clear indication from professional doctors.

The sooner newborns laugh, the smarter they get, this is just a claim, and there is no relevant basis to prove it.

Laughter is just an expression, not a response that expresses the full intellectual development of a newborn. Under normal circumstances, the newborn is generally newborn, as early as about 7-15 days, there may be a phenomenon of laughter, the main manifestation of which is the upturned corners of the mouth, this situation is called mother-in-law laughter, which has no substantive meaning and will not be affected by the outside world.

Often at the age of 2-3 months, there will be a social smile, that is, you can laugh, stop crying to express this kind of recognition of parents and express his happy mood, at this time laughter will have a certain meaning, it can represent a psychological process of his social behavior and the perfection of development.

But you can't just use laughter to completely judge that the child is a sign of being smart, because the child's intelligence needs many aspects to judge.

Such as language, behavior, gross movement, small fine movement, attention, memory, thinking development, etc., these are the embodiment of infant intelligence, of course, the child laughs early is a better phenomenon, but it does not represent whether the child is smart.

The more the baby smiles, the better the physical and mental development:

Parents may wish to amuse their babies more when taking care of them on a daily basis, which is also a natural way to develop their early intelligence. The specific method is: smile at the baby more, or make him laugh with exaggerated expressions, novel toys, drawing cards, etc.

However, making babies laugh is also a science, and you need to grasp the timing, intensity and method, not all the time. For example, when eating, laughing can easily cause food to enter the trachea by mistake and cause choking or even suffocation, and laughing before going to bed may make the baby lose sleep or cry at night. Also, laugh in moderation and don't make your baby laugh too much.
