Allow children to experience the consequences of their acts (within reason) The child who leaves the table during lunch, can be told that the time to eat is when lunch is served. If he chooses to leave, then he will have to wait until afternoon snack to eat again.
Any of these methods can be punishing if done in a way that hurts the child. The key to avoiding punitive overtones is to remain calm, firm, respectful, and confident that changing the behavior is best for the child, you and the other children.
