Height and weight are visual indicators to determine your baby’s growth and development. Although there are individual differences and stage fluctuations in each baby’s growth, there is a certain standard range. When monitoring and recording your baby’s height and weight, mom and dad may want to refer to the “China’s Growth and Development Reference Standards for Children Under 7 Years of Age” issued by the Ministry of Health, and they can easily judge. Note: 1. The table shows the length before 3 years old, and the height at 3 years old and after 3 years old. 2. “Median” indicates the average level of the population; if it is within the range of “-1sd~median~+1sd”, that is, one standard deviation above and below the median, it belongs to the “normal range “, representing 68% of children; if it is within “(-2sd~-1sd) or (+1sd~+2sd)”, i.e., two standard deviations above and below the median, it is defined as “short (tall)”, representing 27.4% of children. If it was within “(-3sd~-2sd) or (+2sd~+3sd)”, i.e., three standard deviations above and below the median, it was defined as “short (tall)”, representing 4.6% of the children. Very few children are within three standard deviations. In addition to height and weight, mothers and fathers should also pay attention to their baby’s “weight standard value of height”, which is an important index to measure the degree of body fatness (whether thin, overweight, obese) and whether it is healthy.
