Children will sometimes act chaotic if they are in a chaotic environment. Secondly, probably the most common reason for misbehavior is to gain attention from a parent or other adults. A defining feature of being human is the need for social contact, approval, and attention that is already present at birth. When parents fulfill this need adequately, a child will feel content and be more likely to engage in solitary play. If a child is not able to obtain attention through positive behavior, he or she may utilize negative behavior for this purpose.
Quality is often more important than quantity.
The concept of rewards and punishments is an integral part of Islamic Aqueedah as there are natural consequences for each of our actions. This same wisdom can be applied to the area of parenting. But if he has intended a bad deed and has not done it, Allah writes it down with Himself as a full good deed, but if he has intended it and has done it, Allah writes it down as one bad deed. Allah's mercy can be seen in this Hadeeth Qudsi and this should be reflected in a parent's tarbiyah as well. Rewards are effective in not only increasing the occurrence of positive behavior, but also in decreasing negative behavior and increasing a child's self-esteem.
