Parents should set the tone
If you are a parent, you would hate to see your children fighting. It is the responsibility of the parents to ensure a peaceful atmosphere at home. Some parents fight a lot and shout at each other in front of the children. Such disturbances at home have serious psychological effects on the kids, who may become violent as a result.
If you have any differences with your spouse, you must talk to him/her in private and not in front of the children. Address your issues gently, without losing patience or self-control.
Do not have a favourite child
Some of the parents have favourites among their children and they do not treat everyone equally. This attitude sows seeds of hatred between brothers and they may not bond or get close as a result.
Wait before intervening
At times, it is better to wait and let brothers solve their own issues. Give them time and space to voice their opinions. They may just be frustrated and will eventually realize their mistakes.
However, you should immediately intervene when you feel that they are getting violent and may get physical with each other. At first, you need to be polite and make them understand the importance of family and forgiveness. However, you may need to be more strict if they persist with such behavior.
Have a code of conduct at home
You must have a proper code of conduct at home and lead from the front by not violating it yourself. Children should know their limits and the penalty for crossing them. Be fair and honest in your treatment of all siblings and favor no single kid.
