Bad attitudes are the worst!! One of the things that we try to do, in order to get to the heart of the issue, is to have Bible verses posted to deal with the bad attitude (we’ve also done this when struggling with sibling fighting). When they are having a bad attitude They have to go and read all the verses and then pick out one to come back and recite and talk about why it is most applicable. Then we also talk about what they should have done in the given situation. Finally, they have to apologize to the applicable person. We have a 14, 11, and 9 year old, and we’ve used this for about a year now. I like this because we bring God back into the situation, helps themw learn to think through their problems first, and make ammends with someone they may have hurt. Depending on the severity of the problem, and how much of a longstanding issue it has been, we may deem this sufficient, or we may deem that more punishment is needed. We do similar to mrsjamiesouth by adding work if they are complaining about school work or being bored, but sometimes, too, we will take things away. If they are complaining about the movie that we may be watching as a family, we make them go to bed early while we have family time.
