At what age do bow legs typically develop, and how can I tell if my child has them?

When your child stands erect, the legs curve outward at the knees while the ankles touch: that's bowleg. Bowlegs occur between birth and 24 months, which is expected as a child grows. At 24-36 months, the bowing starts disappearing. If your child's bowlegs persist after three years, consult your physician.
