Growth trajectory for a child with genetic short stature or constitutional growth delay

Genetic short stature or constitutional growth delay are normal growth patterns. They are characterized by normal growth parameters at birth followed by simultaneous deceleration in length and weight before 2 years of age. After 2 years, these children continue to have low weight and height percentiles but normal or near-normal growth velocity (as indicated by growth parallel to the curves). These normal growth patterns are often confused with poor weight gain.
