Is it normal to dislike a sibling?
Mostly.Normal for most people
Yes, it’s normal to dislike a sibling, even if you share a childhood or a family. You don’t have to be close; treating each other with basic respect is enough.
Siblings can get under your skin like almost nobody else. Clashing personalities, old rivalries, unfair comparisons, or hurtful behavior can all make you dislike one another—and sometimes you simply wouldn’t choose each other as friends.
People’s feelings about siblings vary a lot: some are close, some are civil but distant, and some need firm boundaries. You can care about your family and still not enjoy someone’s company. What matters is how you treat each other and whether the relationship feels safe and respectful.
