Some kids melt down when they don't get what they want, or have to stop doing something fun. It is easier for kids to wait for what they want if they know exactly when they'll get it, so keep a timer or clock on hand. If you know you are going someplace where they will want something they cannot have, tell them ahead of time; suggest that if they get through the outing without complaint, they can have something else. When kids resist stopping a fun activity, try to make the transition easier. For example, as a reward for leaving the playground and going home without incident, stop for a small ice cream treat.
