At present, scientific research shows that the critical period of human brain development is the infant stage of 0-3 years old. At this stage, the development of human brain is the foundation of social field and self-development after its generation. At birth, the total weight of children's brains is 25% of that of adults; 1 year is 50% of that of adults; At the age of 3, the total weight of the brain is equivalent to 80% of that of adults. At this time, almost every baby has overcome the obstacles of language expression and learning knowledge. Before the age of 4, children can reach 50% of the intelligence measured at the age of 17. Some research results show that the average IQ of children who have received early childhood education is about 17% higher than that of children who have not received early childhood education. It fully shows that parent-child early education has a very necessary and far-reaching impact on children's future.

Parent-child early education before the age of two or three is prime time.

According to the authoritative experts from the Early Education Center of Shenzhen University, 0-3 years old is a sensitive period for children's sports, language expression and other abilities to develop rapidly. Parents of young children should seize the sensitive period of their children, cultivate their baby's good character, and let the baby develop its potential to the maximum extent. Therefore, 0-3 years old is the most important stage for the generation of children's sexual quality, and it is also the stage that children's parents need to pay more attention to, and it is also the core stage for the generation of children's personality. If children are encouraged and joined by their parents to realize purposeful intelligent development exercises, under the guidance of teachers, their potential will be developed to the maximum extent, which will get twice the result with half the effort. At the same time, parents' early education at this stage is also a means to promote children's social development needs.
