Standards for healthy children?

Children's health, I just said that physical development, psychological development and social adaptability are normal, and there are no diseases and injuries, so they are healthy. We generally judge whether a child's development is normal. On the one hand, from the perspective of physical development, the most important and commonly used indicators of physical development are height and weight, and the head circumference under three years old is also very important. Through these three indicators, children's physical development and nutritional status can be judged.

Intellectual development mainly judges whether children's neuropsychological development is normal through large amount of exercise, fine exercise, language, adaptability and social communication ability. Judging whether a child's development is normal or not requires corresponding standards. These standards are generally reference standards based on the data obtained from the investigation of normal healthy children. For example, there are corresponding reference standards for physical development, and the development level of children can be judged by comparing the corresponding standards. Psychological and intellectual development also has corresponding scales to evaluate, and some more important development indicators can also be used to judge whether a child's development is suitable for the corresponding age.
