I'm probably the worst mother ever. I'm at least a little unconventional. When my twins were in the fighting stage I told them they couldn't play together anymore. I put them each in a separate area to play with the exact same toys. I fed them lunch separately and on and on. Before you know it they were begging me to put them back together and they rarely fight now.

I always have to remind myself that it's just a stage. They'll blow through it in a little while and be playing together again like best friends. I think that what Mom 'O Twins said was great. It gives them time apart and keeps the peace. I have definitely told the boys I nanny for that they can't play together if they're going to fight. I give them a few options of things they can play seperately. The other option is to take them to a big playground (or even a field) where they can just run and get away from each other. Good luck. The fighting stages are tough.
I write a blog called Nanner! Nanner! Nanner! about nannying twins if you're ever interested: http://nannernannernanner.blogspot.com

Hello,

 I see you have Twins. I also have Twins.

I thought I would invite you to join our group called "Mommies of Multiples".

We would love to have you.

Have a Great Day :-)

Oh, as for the fighting, like someone else said, I had to split my girls up for a while. It was the only thing that worked for them.

I agree seperate them if you can or take them to a field where they can run that off. It is a stage that will progress into more stuff. Like who will sit where at the table. The other day we had a blow out because one twin thought the other was copying her for getting the same drink at resturant. I ate with one twin in the play area while the other was with dad on the otherside of the resturant. My husband and I talked to each other via cell. Life with twins yayyy!!!!!!!!
