Q. How long will it usually take for a child to change his behavior?
A. There's no exact time frame, but I tell parents to work on one behavior faithfully for a few days to master the method. Once you get the behavior to happen five times and you enthusiastically praise it five times, you'll probably begin to notice some progress. It'll keep improving after that. And while you're focusing on that one issue, handle other misbehavior the same way you normally would. After the first problem is gone and you're comfortable with the program, you should be able to work on two or three different behaviors at a time.
