Aren't kids funny and weird sometimes? :) Here's a few ideas... The Discipline Book by Dr. Sears has a chapter on annoying habits that might be helpful. How about give her a cup with a straw, and make her "drink 3 big swallows" before she talks for a week or so? If that doesn't work, maybe she's old enough to say that spit grosses others out, and it's a private matter, therefore she may visit the bathroom frequently and deal with her "issue" with the door closed, or learn to swallow and be with people. That sounds kind of harsh, but it might do the trick if you think she's old enough. Good luck!
