It will take a long time to see the obvious effect. The specific judgment method is that the overall quality of successfully educated children is obviously higher than that of children of the same age; It's not how many words a child can read, how many poems he can recite, or what portraits he can draw. The importance of early education has been confirmed by many physiological research results. It is found that infancy is the most critical period for children's nervous system development and various potential development, and it is indeed a good opportunity for education. Among them, 0 to 3 years old is the golden age of baby early education, and it is very necessary to give baby early education at this time. Moreover, during the period of 0-6 years old, the baby will experience sensitive periods such as lips, hands and feet, space, negation, property rights, identity, language, senses and movements. Early education is very helpful for children to get through various sensitive periods. Parents are advised not to worry too much about how long early education will be effective, but to spend energy choosing reliable and professional institutions. When choosing, we should objectively understand the situation of the institution and choose the one that is suitable for children rather than the most expensive one; Experience the teaching environment personally, safety is the most important, and interactive experience teaching method is the best. Secondly, when parents choose an early education center, they should examine whether the curriculum is scientifically divided into age groups, and the curriculum emphasis at each stage should be different according to the development of children's ability.
