To determine whether your child’s height is normal or not, you should think about the following aspects: 1. Accurate measurement. To accurately measure the child’s height; 2, have a reference standard to do comparison. Nowadays, the reference standards are often used are issued by the state, that is, using Chinese children’s height data as the standard for comparison; 3, not only with the standard to compare, but also with the child itself to compare, that is, the child’s own growth potential, genetic height, and now its own growth pattern. Only by comparing these three aspects can we accurately grasp whether the child’s height is normal or not. Sometimes in clinical practice, we often come up with an example to explain to parents, for example, if the parents are the same age as Yao Ming, can they compare their height with Yao Ming’s child? Because of the genetic differences, the standard of the child’s height is not the same. And do all children have to compare their height with the national average? It’s not just that. Every child has a very stable growth curve from birth to adulthood, and it’s more accurate to compare it with the child’s own before and after.
