I've found that a stricter teacher generally has better control with the kids, and they typically like that teacher better than one who lets them run rough-shod all over the place.
Interesting development on that front. Last night the kid I talked to last week was better, still a little unfocused but definitely better. The interesting thing to me was that he was coming to work with me all night long. He asked me questions on etiquette and technique and seemed to listen. I mentioned this to a teacher friend of mine (non-aikidoka) and she said it may be because by taking him aside and talking to him that I showed an interest in him and his progress. Hmmm, I'll have to wait and see how this turns out.
