It's a pretty impressive statement abot Dot that he can ride her through pretty tough obstacles like that water.... seeing as how she is so young herself. I see he carries a crop, to let her know he means business even if he's small :~D
Not having kids, I never know how much to expect they can handle! I know that kids who are allowed big tasks, like handling a horse, can take on many things that more cautious people would cringe at.
