Discipline is the process of teaching your child what type of behavior is acceptable and what type is not acceptable. In other words, discipline teaches a child to follow rules. Effective discipline uses many different tools, like positive reinforcement, modeling, and a loving and supportive family. It sounds so straightforward, yet every parent becomes frustrated at one time or another with issues surrounding children and discipline. Children are not born with discipline. They have to be taught. The ultimate goal of discipline is to develop self-discipline.
