Scientific early education refers to the early learning from birth to the pre-primary stage. It is an education that promotes the full development of intellectual potential and social adaptability according to the objective laws of children's psychological and behavioral development. The baby's brain develops fastest in 2-3 years after birth, approaches the adult's brain weight at the age of 3, and then the development speed slows down. Therefore, it is necessary to grasp the critical period of infants' intellectual development and use the sensitivity of their cranial nerves for early education. I hope my answer is helpful to you, and I wish the baby a healthy growth.
