I remember taking my son (who had done nothing but travel baseball all the time) up the South Brothers col in the morning when it was super firm. Was an interesting place for him to use crampons and an ice axe for the first time. He did fine, but I did question my decision making for a couple minutes. I mean, it wasn't that bad, but definitely and interesting experience for him especially since he had a broken hand. He was older than 9 though....
