This issue is more about your husband than your boys. If you can get him to agree to change, then your boys will change. Does he want to change and can't or say he doesn't want to change?
Heres what I did recently to combat an issue in my house. When my DH has a bad day, he comes home and yells at me and my daughter over little things that didnt bother him the day before. He learned this from his father who learned this from his father. Our daughter has begun this bad habit. This issue has been a problem for him for a long time, but now that there are two of them doing this, I am not happy. When I have a bad day, I do not verbally vomit on my family. This is a self-control issue, just like using potty words.
I waited until I was not angry and neither of us were tired and then I merely stated some facts to him. I didnt share my opinions or use the words never or always. I began with, I have a problem and I need your help to fix it. The problem is our daughter is copying your bad behavior. I would like you to have a talk with her and let her know that you are not being a good role model and that neither of you should be hurting people you love when you have had a bad day.
He was very humbled instead of defensive because of my attitude and timing.
He talked with her just like I asked, and both of them have really made strides in improving. One day when he blew it, I was able to tell her, Remember when we talked about this? This is not acceptable behavior for anyone, including Dad. We prayed that he would feel bad and apologize to us and that we would forgive him. The next morning he went to work before we got up. When he saw us, he was so contrite that he ran to us to apologize. He picked up our daughter and said that he was so sorry. She put his hand on his cheek and said, We hoped you would say this. Of course we forgive you. We prayed about this last night. I was SO PROUD of my little family. We are teaching her that her parents arent perfect and that self-control is an issue for everyone.
Really, isnt all of life learning self-control? Isnt parenting all about being a better role model than our parents were to us? My parents were awesome but I can remember ONE TIME that my mom apologized to me and no time when my dad did. Every parent makes mistakes and if we don't apologize to them, then how can we can we expect them to apologize to us?
Best wishes communicating with your husband. You are starting off much better than others since you all love each other. Imagine if he didnt love you or the boys.
