An infantometer is a medical device used to measure the length or height of infants and young children. It is commonly used in pediatric settings to assess the growth and development of babies. The device typically consists of a flat surface with adjustable measuring boards to ensure accurate and consistent measurements. The child is usually placed in a lying position (for infants) or a standing position (for older children), and the length is measured from the head to the heel or from the feet to the top of the head, depending on the design. Infantometers are essential tools for tracking a child\'s growth and can help identify any potential health concerns or developmental issues.
