If i want my child to stay positive, how do i punish them when they are in the wrong positively?

Firstly you have to be clear about your emotions when you punish your child - note that you are not doing it out of frustration or anger but more of meeting out justice for example. It is important to tell the child why he/she is being punished and Ensure that you are as air as possible (if other children are involved) and the punishment is appropriate. This is so that they know that they are punished for their wrong doing and not being targetted for their own being
