The brain capacity of 0-year-old is equivalent to 50% of that of adults, and that of 3-year-old is equivalent to 80% of that of adults. 50% of a person's learning ability is developed in the first four years of his life.
Now it has been scientifically proved that the critical period of brain development is the infant stage of 0-3 years old. At this stage, the development of the human brain forms the basis for the future development of intelligence, emotion, sports, social and other aspects.
At birth, the brain weight of children is 25% of that of adults;
1 year is 50% of that of adults;
At the age of 3, the weight of the brain is equivalent to 80% of that of an adult. At this time, almost every child broke through the barriers of language and learning.
Before the baby is 4 years old, it can reach 50% of the intelligence measured at the age of 17. The survey results show that the IQ of children who have received early education is about 17% higher than that of children who have not received early education.
It can be seen that early education has a very important and far-reaching impact on children's future. I hope my answer can help you.
