what should i do?

Hide your things. Get a footlocker & lock your things in it.

How old is your brother? How old are you?What kind of stuff?Go get a box big enough to hold your stuff and lock it up- even the stuff he already took!!

When you put your stuff up that you don't want him messing with then make sure it is in a closet that can be locked or something like a chest. Good luck.

Everyone wants/needs/desires attention. Some more than others.

Try playing with him more. Play with your stuff with him. Pay more attention to him and be his best buddy and his big "look up to" brother.

Try it.

It's better than chasing your stuff and being upset.

Isn't it?

Hey , its afterall your brother. If you really find him enjoying with your things, you enjoy seeing him enjoying.

If you have your own room get a lock on your door.

well you need to set him strait look my stuff your stuff move it or lose it ..joke ..let him know that its enough.. and dealt with your moms/pops... smile..

take it back from him or just tell him to give it back to you. Good luck!!

Do you have parents? If so then tell them.
