Parent's actions and decisions can greatly affect sibling's relationships. I have found that organizing their play area so that you don't have a lot of small pieces floating around limits the squabbles. I try to have a lot of cooperative toys that they can use together, and to have enough that they can share without a lot of problems. Yet on the other hand, it is a good idea to separate some personal items so a child can gain a sense of belonging. When siblings do argue, it is good to teach children to use their words instead of grabbing or yelling. Teaching them to work things out in a co-operative way.
I have used this positive approach for years, and it fosters the ability for a couple of kids to compromise and negotiate a fair result to their "battle". When a squabble occurs, sit both children down next to each other, together on the couch or in two chairs facing each other. I explain that they cannot get up until they have arrived at an agreeable solution to their problem. You may need to arbitrate initially. Then back off and let them problem-solve their problem. If they can not come up with a solution, suggest some possible ideas for them. Their negotiation skills will improve with time, and you have the added bonus of not having quite so much tattling.
My English teacher always says, "I consider it a blessing when I see my children arguing." To an extent, I do agree with him. Disputing and even light fighting is necessary to relieve the stress and aggravation between siblings. We must be careful to make sure it doesn't go too far, we don't want anyone to get hurt, but a lack of this disputing should tell us that there is something wrong, because we all need to relieve our stress, and arguing is the best way to do it!
