Knocking...NBR

lauranoelle09

I'm a lurker mostly, and this is not birth related, but I thought you ladies could help. I've been having a problem ever since I moved into the apartment next to my brother. He WALKS in my house ALL the time without knocking and it drives me crazy! He's very sweet and family oriented so he thinks we should all be comfortable with each other, so he isn't trying to do harm, but I've told him multiple times not to just walk in. I'm afraid one day I will be doing something personal and he'll walk in. My question is, what should I do now?? I've already told him not to and he still does it. I'm also afraid to keep my doors locked during the day because if they can't walk in, he or his wife will stand there pounding on the door, and wake up my son from a nap half the time. Should I just be more firm? Tell him he's not allowed here anymore if he can't follow rules?
