📘 About the Child Calories
Children need energy to grow as well as to move. This calculator uses the Institute of Medicine's estimated energy requirement (EER) equations: weight-based for babies and toddlers, and age, weight, height and activity for children 3 to 18.
It also suggests a healthy split between carbohydrate, protein and fat and how to spread the calories over meals and snacks.
