Teen's don't get on.

[EleanorLavish]

My eldest two squabble all the time. They cannot walk past each other without one of them muttering something rude to the other.
They sit on the sofa and squabble, move your feet/you stink/stop eating near me type nonsense. If we go out in the car they argue over who sits where, if one asks to go somewhere the other will come up with reasons why we shouldn't, if one turns on the TV the other complains about whats on until massive row erupts. They slag each others friends off. They laugh at each others hobbies. They never, ever, ever support each other, or say well done. They hate to see the other succeed.
They ruin days out, and really seem to hate each other! They also vie for youngest child's attention and affection.Causing more rows!
Has anyone managed to help teens to get along? Stop squabbling? Should we try for family counselling?
Any advice would be great.

Two of mine literally hated each other and I mean hated. It's normal, I remember hating my sister! I don't think there's anything you can do, just weather the storm.

The two of mine who hated each other are now the very best of friends. They see each other two or three times a week, go out to gigs and the cinema together.

It will pass. They may never get on but they grow up.

Thats what I'm hoping Hydro. My own DSis and DBro fought like cat and dog and get on well now. I hate the hate though!

Same in our household with my 2 teens
I’ve now resorted to keeping them apart as much as possible, and dropping any attempts to do activities as a family together. They’re both in that grumpy phase of their teenage years, and are pretty hard work generally anyway! so hoping they will grow out of it to a level where they can at least learn to be civil to each other!
