Girls, Girls with brothers!! Please help me?

My brother is going through puberty and he is so rough now and getting so much bigger then me! I have told our mom but she just says "boys will be boys" and ignores it. He keeps hitting and kicking me and trying to wrestle when I don't want to and he does it to hard now.

I need to get him really good to make him know I'm not messing around. I tried punching him in the face but he is so much taller then me now that I can't reach his face without him dodging.

What can I do? Have you done anything to your brother's to make them cry or afraid to fight with you? How?
