Many young kids have flat feet, toe walking, pigeon toes, bowlegs, and knock-knees. As kids grow, some of these conditions correct themselves without treatment.
Flat feet usually don’t cause problems. Doctors only consider treatment if it becomes painful. Occasional toe walking should not be cause for concern, but kids who walk on their toes almost all the time and continue to do so after age 3 should see a doctor. Children who intoe and trip often may have internal tibial torsion, in which the lower part of the leg is rotated inward. Bowleggedness (also called genu varum) is an exaggerated bending outward of the legs from the knees down that can be inherited. It’s common in infants and, in many cases, corrects itself as a child grows. Most kids show a moderate tendency toward knock-knees (also called genu valgum) between the ages of 3 and 6, as the body goes through a natural alignment shift. Treatment is almost never needed because the legs usually straighten on their own.
