There are many people that have flat feet and never face any problems with their feet. If there is a family history of flat feet with family members needing surgery or having bunions, hammertoes, or other foot conditions, then YES, your child should be treated. This does NOT necessarily mean surgery. Your child might need something as minimal as a good insert recommended by their podiatrist. The BEST thing to do is to have your child’s foot examined, then you will be able to go from there to find the best treatment option.
