3rd Grade Weight: What's a Healthy Range?

It is not possible to say definitively whether or not a 3rd grader is supposed to weigh 75 pounds. The weight of a child depends on a number of factors, including age, height, gender, and genetics. Some 3rd graders may weigh 75 pounds, while others may weigh more or less. It is important to talk to your child's doctor about their weight and to make sure that they are growing and developing healthily.
