1, perceptual motor stage (birth -2 years old). Equivalent to infancy. This is the stage before language and representation come into being.
2. Preoperative stage (2-7 years old). This stage can be further divided into two small stages: symbolic thinking stage (2-4 years old) and intuitive thinking stage (4-7 years old).

As soon as the child is born, parents must start thinking and planning the education and guidance for the baby in advance, because when they leave the mother and come to this world as a completely independent body, their five senses will be opened and the baby will be conscious. Moreover, the characteristics of each stage are different, and the education methods are different.
Children who are in the stage of perceptual movement before the age of two perceive and explore the world mainly through innate conditioned reflex and movement. Babies aged 9- 12 months have often been able to acquire permanent perception of objects, which is the first step and the most important progress in their cognitive development. Babies at this stage need their parents to interact with them frequently, and at the same time they can be stimulated by rotating toys and other tools.
(2-7 years old) The most self-centered child is often the most stubborn child at this time. One is one, one is two. Their minds are often filled with many strange ideas. Because of their cognitive limitations, their greatest cognition is themselves, so they will also regard everything in the world as another living and perceptual spirit like themselves.
(7- 12 years old) The most logically developed children's cognition has reached the level of independent and simple backward reasoning. At this time, parents should start to give their children more "thinking" and listen to their opinions and opinions.
12 years old+) is the most adult. They no longer only see the real and concrete things in reality, but their thoughts and propositions have become part of their thinking. At the same time, children learn the reprocessing of thinking and can fully grasp the logic of thinking.
