Where should you mark when measuring a child?

Measuring a child's height accurately is crucial for growth assessments, and the appropriate points for marking this measurement are at the top of the head and the heel of the flexed foot. When measuring height, the child should stand straight with their heels together, looking straight ahead, and the body in a neutral position. The mark at the top of the head indicates the highest point of the child's height, while marking at the heel ensures that you are measuring from a consistent point that accounts for the position of the feet.

Using these two points provides a precise and standardized measurement that helps in comparing the child's growth to normative data. Other body parts mentioned in different options, such as the waist or knees, would not contribute to an accurate measurement of height.
