The measurement method of pediatric height is as follows: 1. Children under 3 years old: take the prone position, with the top of the head against the stopper, and the pillow, buttocks and heels close to the measuring board, and measure the height accurately through the scale of the measuring board; 2. Children over 3 years old: take the standing position, with the pillow, buttocks and heels close to the measuring tape, and measure the height accurately through the scale of the measuring tape. When measuring height, pay attention to take the same time and the same measuring tool to reduce errors, measure once every 3 months and record the growth curve table, which can clarify the growth rate of children, and if the growth curve shifts significantly upward, abnormalities such as premature maturity can be detected in time.
