When taking your child to the theater, make sure they understand the rules of the game: no loud talking, no fussing and carrying on, no interruptions. Make sure your child understands that the characters on the stage are people in costumes, playing make-believe.
One way to save money on a theater experiences is to attend a performance at a local college or university. The price is right, and while the actors may not be the most polished you've ever seen, their performances tend to be earnest and entertaining.
