Since young feet are still growing, problems can develop quickly. It is important to catch any conditions before they continue into adulthood. Pay attention to the following as they might indicate possible foot problems your child is experiencing: a change in the wear on their shoes, discoloration of the skin or nails, bumps on the skin, a change in the general coordination and stamina of your child, falling and fatigue and/or if they become unwilling to participate in activities they normally enjoy.
