How much weight gain in childhood is too much?

After a child’s third birthday gaining more than 10 pounds annually is concerning and deserves attention (though not every child who gains more than 10 pounds in a single year is gaining excess weight). Generally children grow or “track” along a stable growth curve trajectory. If a child begins to cross percentiles on the BMI or weight curve (“jump” from one curve to another), this becomes a cause for concern and evaluation by the child’s doctor is advised.
