My son Zach has pffd on his right leg. We met with Dr. Davidson on 5/6 and we now have a timeline for his first surgery. Zach needs an inch orthodic list (which i am attempting to accomplish) and he will have two surgeries. The first surgery is to be when he is between 4 -5 years old. Its definately different. i see my little man walking on one set of tippy toes but boy does he move. i really want to get him sandals for the summer but really dont know if i can being he needs a lift. I'm going to try. can anyone share as to what i can expect now that he is moving?
