When do kids learn to like their siblings?!

[MrsRossPoldark]

I have just finished yet another half hour of listening to my 3 DSs shout like idiots at each other during family dinner:

Shut up
go away
Leave me alone
I hate you
P@ss off
Stomp upstairs
Slam doors
Don't you treat my house like this!
... And repeat ad infinitum

When do I throw the bloody lot of them out & lock the doors (or do I drive off in the car to have a good scream & come back when one of them - or DH - realises I've gone?)!

Mind you they probably wouldn't notice / care.

When do they grow out of this stupid phase as it's driving me insane, esp as I have to cope with it by myself 5 nights a week whilst DH is working away from home & it doesn't stop when he's here.

When my db (2 years older) left the family house to go to college. I was 14 and had hated him up till then. Sure the feeling was mutual.
We became instant friends and I adore him now (30 and 32)
To be fair he stayed away and I am lucky to see him 4 times a year for between 3 days and a week.

Feel for you, I know how it feels to be constant referee in your own home and that's with DH and 1 DD
