C.,
I have four kids age 8,almost 7, 4 and 2. Does that count as a large family? I have noticed that most current parenting advice is geared to someone with one or two kids and is often impractical or impossible to implement with a large family. I kind of had to do a lot that just worked for us.
I learned early on that my kids would start fights with each other for my attention. Dropping whatever I was doing to give them a repeat of the "let's share, get along, talk it out, etc. etc" speech just played into what they wanted. It's important to teach that principle from the beginning, but it isn't always the problem - especially when they know better and continue to fight.
In order to stop the fighting, it has to be more unpleasant for them than getting along. They already know that a good solution for a fight over a toy, computer time, etc. is to set the timer and each person gets equal time with the coveted object. They can "rock, paper, scissors" to see who goes first. If they want to fight about it, everyone gets to put their nose on the wall for at least 5 minutes and the coveted item is off limits for everyone until the next day. No lecture, no begging for them to behave, no reminding. They know how to behave, they just need consistent consequences and actions speak way louder than words.
We have also had to work a lot on tattling. If you tattle, you get the consequence of the behavior you tattled about. We make it very clear that if someone is bleeding, seriously injured or is about to be, that is not tattling and we want you to come to us. Tattling is telling with the intent of getting someone in trouble, and if you tattle, you get the consequence you intended your sibling to get.
After the fight is over and everyone has cooled down, I have the kids tell each other they are sorry and they shake hands. Then can be the time to talk about how to choose differently to avoid the same consequences next time, but that conversation definitely has to happen after the punishment and not before. The important message is that YOU made this choice and YOU chose this consequence and YOU control what happens to you next time because YOU make the choice. It has nothing to do with mom and dad and siblings. So take back YOUR power and make the right decision next time.
There are preventative things you can do as well. There was a time when I had to seperate my kids every night when I fixed dinner. I knew they were going to fight every day, so BEFORE it started I sent them both to a separate room with something to do and they couldn't come out until it was time for them to set the table and eat.
I give them each a little space of their own and we have a lot of separate bins for things - everyone gets their own bin for their hats, mittens, etc. They get their own shelf on the shoe rack. Everyone can get their own bin of bathroom accessories (toothbrush, comb, hair clips, etc.)
You can call a family council and work out a system on what grounds you can borrow things and what is considered community property. Let everyone contribute to what they feel are appropriate rules, limits, etc. In the end, you all want the same thing. It's just everyone sees a different road to get their and you, as the parent, have to remind them that their road cannot include trampling the rights of others.
Also, we schedule a lot of things out and rotate stations in the house. Two kids shower and bathe while the other does homework and the youngest plays. Then they swap. If they are all in line to use the bathroom or all trying to get my help with homework, or all get their free time at the same time and want to use the same things, there is frustration. I know a lot of families schedule computer time - 7:15-7:30 is Jennie's time, 7:30-7:45 is Bob's, etc.
Good luck,
S.
