I have seen this challenge in many families, and sometimes the roles are reversed. Most children will test their boundaries, this part of their environmental growth. The best advice I give my karate parents is consistency, the more consistent your message, the better the results you will have with your children. Many times the message is different from one parent to the other. If one parent has clear-cut boundaries, the children understand and respect those boundaries; they also feel much safer with that parent in a crisis. If you tell them you are going to do something and you do not, they remember and they start losing trust in your word. They feel they can do what ever they want because you will not discipline them and if you do, you will let them out early and they will be back to what they were doing previously.
