Don't remind him or make him sit on the toilet against his will. This fosters a negative attitude. Other family members may also praise the child. Provide a prearranged reward if your child stays clean all day. The favorite reward of many children is 30 minutes of free time with either parent, doing whatever the child chooses.
Incentives build motivation to succeed.
Respond gently to accidents. When your child is soiled, he should clean himself and change into clean underwear. Don't blame, criticize, restrict, or punish your child for accidents. This may cause him to give up, as well as lead to secondary emotional problems. Don't allow siblings or others to tease the child.
