Reinforcement. Give positive reinforcement after good behavior so that your child will want to repeat it. It is important not to accidentally reinforce the problem behaviors. If your child throws a temper tantrum for attention, don’t give him/her that attention. If you do, this behavior will only be repeated.
Love. Children react best to their parents when there is a sense that the parent loves and values them. For every negative comment or correction, there should be at least 10 positive comments.
Be clear. Make sure your child understands what is going on. Give clear, concise, age-appropriate instructions about your expectations and the consequences for meeting them or not meeting them.
Set up for success. Do everything to make it unlikely that the problem behavior can happen. For example, if your child is playing with breakable objects, try placing those kind of objects out of his or her reach.
Organize. Start with a simple plan, stick with it and track its progress. If you don’t see improvement, shift gears and try something different based on what you have learned.
