I'd say this depends a whole lot on the child. If she's the forceful type who will yell and scream and complain but never give up and do it anyway, you might get away with clips. If she's anything at all like my son (and me) - make it easy, as easy as it gets. I learn best from automating the things I can do easily and well before trying the things I can juuust manage, and I learn nothing at all from the things that are just a bit too hard.
Winter riding is much less about badassery and much more about bundle-uppery. - malkin
