But there's a different type of expertise and expert knowledge, that isn't often regarded as such in our society: I was wondering if Margot Chu and her husband Al can walk their 5-year-old daughter to a nearby school, or if it would be too far. So I asked in r/AskParents, and got back some lovely answers. Much thanks to those people, who shared their hard-won knowledge! https://www.reddit.com/r/AskParents/comments/12oo7u9/can_a_5yearold_walk_25_of_a_mile_how_long/ 2/2
