It is more scientific to use growth curve to detect the development of a child's height and weight than to judge whether a child is tall or fat simply by a number. The whole curve consists of several continuous curves, and the bottom curve is -3. If the baby is below this level, there may be growth retardation. The top curve is 3. If the baby is above this level, there may be overgrowth. Both situations should be concerned. The middle curve is 0, which represents the average value. Draw the measurement results of height and weight on the growth curve to form a curve. Some children grow faster and the growth curve is diagonal. As long as it is within the normal range, there is no need to worry.

Four understandings of the need to subvert the growth and development curve

Whether the baby's height and weight are up to standard depends on the height and weight table. Subversion reason: this is not accurate. The absolute value of height and weight is of little significance. It is important to understand the changes in children's growth and development through these values. Only in this way can we have an objective evaluation of children's development.

Using growth curve to monitor baby's growth and development is actually a linear, long-term and effective management of baby's growth and development. Through the change of growth and development curve, the problems existing in the baby's growth and development can be found in time; And regularly checking the height and weight table can also judge the baby's growth to a certain extent. However, it is difficult for us to combine several results to evaluate the baby's growth, and we can't observe the "abnormal" change of this curve.

2. "Standard baby" is the most normal.

Subversion reason: If your baby is not a "standard" baby, don't worry! The new indicators released by the World Health Organization only describe the "average" state of infant growth and development in different countries. According to the recommendations of the World Health Organization, countries will formulate new standards that meet the growth conditions of their children. At the same time, the standard weight and height will be different in different periods and regions. Even local standards need to be constantly adjusted. Every 10 year in China, children and adolescents aged 0 ~ 18 years old are selected in the north, middle and south to conduct height and weight survey and statistics, and the height and weight of Chinese children are obtained by combining various feeding methods. The latest survey was conducted in 2005. In addition, there are certain individual differences between each baby. His growth path may be influenced by many factors, such as nutritional status, eating habits, heredity, diseases, environment and so on. Therefore, it is difficult for us to completely control the baby's growth trajectory like producing product parts. At the same time, the average curve is not the standard to judge whether the baby is developing normally or not. As long as the baby's growth curve has been within the normal range, it is normal to grow at a constant speed.

The oldest baby is smart.

Subversion reason: Although we said earlier that the head circumference is an important indicator reflecting the baby's brain development, it does not mean that the bigger the baby's head, the smarter it is. Whether the baby is smart or not is not directly proportional to the size of his head circumference, as long as the baby's head circumference is within the normal range. If the baby's head circumference is too large, it is beyond the normal range, but it should arouse the vigilance of parents. It is best to take the baby to see a doctor to help find out the reason.

As long as the height and weight are within the normal range.

Subversion reason: In addition to monitoring the baby's height and weight separately, we also need to take care of the baby's body shape. Although the height and weight are in the normal range, the calculated value may tell you that your baby is obese or malnourished. Therefore, we should also monitor the baby's body mass index (BMI). This will not only ensure the baby's nutritional status, but also make the baby "stylish"!
