For the kids, here is one technique that I use and they really love it.
First, soak the ribs for 24-48 hours in cherry coke. I like to puree maraschino cherries and mix with Mexican Coca-Cola, as that is cane-sugar based. But you can use any brand of corn-syrup based cherry cola in a pinch. You can even use Dr. Pepper if you like the taste of that. I don't. Just don't use diet.
After that, you may or may not use a mild rub. When cooking, spritz or mop frequently with the cherry coke, and smoke as usual with cherry wood. What you are going for is a carmelization of the sugars on the outside of the ribs. Kids usually like them falling-off-the-bones tender, but you may use discretion.
