Good to hear Charlie is doing good , and go to go home.
My friend's son was born with two club feet, they did not get good treatment until they got him to Shriner's hospital when he was about 18 months old. He had 2 surgeries, and he had a cast on for a good few weeks. Whenever we were out, people kept saying things like poor thing, what happened, and one day I lost it - told one little old lady he had broken it skiing last week!
By the time he was 6 or 7 years old, he was playing hockey and soccer like the rest of them, and you wouldn't know anything had ever been wrong, unless you knew to watch for him toe-ing in when he was really, really tired. As a 2 and 3 year old, he wore 2 different-sized shoes, and he didn't have a left and right foot, he had a small foot and a big foot! His parents bought the same make and model of Nike high-top runners to start with, and he wore one from each pair; as his feet grew, he would get a new pair, and wear the unused one from the "old" pair and one from the new pair, and so on . . .
