Yes, I have... but only if they allow me. No holding kids down. Usually it's the ones that hurt (like on their backs or in the ear). I have one son who will not let me near him and of course, he has the worst acne. We've tried everything over the counter (acne.org, etc.) but to no avail. Now he's just in the giving up stage and he's an adult so there's not much I can do without being an annoying nag. I think it's allergy related, but he doesn't even want to hear that.
