Does sibling rivalry ever end?

Yes it's normal. And i dont think that it ends although it may not be as intense as it was when you where younger. My younger sister and i continue our rivalry even to today, although i must admit that i'v instigated some of the issues.I'm fortunate though because we are close despite our differences. After all she,s the only sister that i have and that makes her more bearable.

I guess it is difficult to define 'normal' when it comes to families and the dynamics within. My younger sister and I still don't get on as adults and if anything I think the division is worse now we are older. I know people who get on really well with their siblings and those who can't stand the sight of each other. I guess it depends largely on the personalities as I have often said I would never choose my sister as a friend because we have such different views and values.

i think sometimes that end in childhood. but still there are few who are rivals all through the life. it depends on the nature of the person.some can't get over it a sthey take it too seriously.

no not really
