1.What are developmental variants? There are some common problems during normal child development, including flexible flat feet, inward pointing of the toes, outward pointing of the toes, inward knee roll and outward knee roll. 2. Why do infants and children have these variations? In many children these changes are part of normal development and may be inherited or first seen by the whole family. Unfortunately, some abnormalities that are hidden in underlying disease are not detected, and your doctor will help you identify which changes are not abnormal. 3. What if our parents or grandparents insist that we do something for our child? (1) Do not be overly concerned about those variations in your child, as this can make your child feel defective. (2) Encourage the child to be more active. (3) Give the child a healthy diet to prevent obesity due to excessive eating. (4) Give the child loose fitting shoes so that the feet can move adequately.
