What is the proper way to weigh infants?

Weighing infants accurately requires specific techniques to ensure that the measurement reflects their true weight. Weighing an infant without clothing or a diaper while lying down on an infant scale is the preferred method because it minimizes any extra weight that could be added by clothing or additional items. Infant scales are typically designed for this purpose, providing a flat surface that is safe and comfortable for the infant.

Using clothing or even just a diaper can introduce variability into the weight measurement. Clothes can vary significantly in weight depending on the fabric and amount, leading to inconsistent results. Additionally, options that involve the infant being seated or standing are inappropriate as they do not accommodate the infant's size or development stage. Infants are not able to stand or sit securely on regular scales, which would also not provide a safe or accurate measurement.

Thus, weighing infants lying down on an infant scale, without clothing or a diaper, ensures the accuracy and reliability of the weight measurement.
