I am 25 and my midddle brother is 22 so when we were kids I unfortunately beat the living daylights out of him. It's not that I didn't love him it was something that I just did. He retaliated and we went through some crazy things like choking eachother, tying him up, stuff like that but he is one of my best friends. sometimes I like to take credit for making him as tough as he is. I think it's normal but my parents corrected me each and everytime and him as well. It is not right to those things to anyone but it does happen. Just keep an eye on them but eventually it should disappear.
