They make a commercial Dr. Pepper Bar B Q sauce that is on the shelves of most stores. I tried it. It's a little spicy for most kids. When cooking for kids I have a sauce we make we call Southern Belle. It has Southern Comfort in it. With the kids we substitute Nehi Peach soda for the Southern Comfort. Kids love it.
