This article is written to assist and provide support to parents and teachers involved with behavior issues that are causing some concerns both at home and or at school. There is much that can be done to help, however; the focus here is on the preventative approach which is key to maintain positive behaviors.
A consistent approach when dealing with children with behavioral concerns most often leads to more productive and positive behaviors. It is highly recommended that you plan strategies that you can implement regularly. Whether the child is acting out, involved in conflicts, bullying, or being verbally or physically aggressive; it is important to ensure that you have positive interactions and that you refrain from calling the child 'bad', it is the behavior being exhibited that you are unhappy with and the child needs to know it is not him/her it is the behavior. Acceptable and appropriate behavior is developmental - it happens over time and is greatly influenced by parental support and guidance, peers, previous experiences and the intervention techniques employed by teachers, caregivers and parents. As 'Dr. Phil' often says: "You teach people how to treat you".
