Normal Weight and Height Guidelines

Parents often wonder about the normal growth of their children. While general guidelines can be followed, always remember variations are the norm with kids! Typically, height doubles between 3 and 4 years old; then, it triples by 13 years old (based on height at birth). Weight usually doubles by about 5 months of age, triples by 12 months of age, and quadruples from 2 to 2 ½ years of age (based on weight at birth).
