Is it normal to fight your brother?
Mostly.Normal for most people
Yes—brothers arguing or getting on each other’s nerves is very common. If fights regularly turn physical, frightening, or cruel, though, that’s more than ordinary sibling squabbling and deserves attention.
Brothers can clash over all the usual things—space, attention, chores, or just pushing each other’s buttons. Even siblings who love each other can argue, especially when they spend a lot of time together.
The line is how it happens and what comes after. A disagreement or occasional heated spat is one thing; repeated hitting, threats, intimidation, or someone feeling unsafe isn’t something you have to write off as “just siblings.” If that’s happening, tell someone you trust and get help setting safer boundaries.
