This pamphlet presents guidelines and tips for parents on setting limits for the behavior of young children. The need for limits and the goal of teaching children self-control are explained. Some general guidelines for limit setting are provided which include making the limits age-appropriate, recognizing the child's need for practice and repetition and to test or try out new limits, and understanding the importance of follow through and a calm, definite attitude. Next, specific tips for setting limits are presented: (1) be specific and clear; (2) be simple, brief, and to the point; (3) state directions positively; (4) use hard-line phrases selectively; (5) offer alternatives for unacceptable behavior; (6) replace threats with clear expectations and consequences; (7) eliminate questions you really don't mean to ask; (8) avoid labeling; (9) avoid ambivalent words; (10) replace authoritarian words; (11) offer choices when possible; (12) avoid comparisons with other children; and (13) use external references (e.g., clock, activity, signal) for setting limits. Additional suggestions concerning timing and limit setting include establishing routines, pointing out the sequence of activities, allowing time for transition from one activity to another, recognizing that it can be hard for children to stop an activity, and preparing children for new situations.
