HI! my grandaughter is now 12 but used AFO's whenshe was your son's age.She used them until she was about 7yrs.old, now uses nothing to aid her. She has been with me since birth and is such a joy. There are bladder and kidney problems now that have developed over the years. She has had several surgeries since birth and is facing more but I would not trade her for the world.
