Venting about parents

Okay, so I have a very unique name picked out for a boy if I have one. I love it and so does my fiancé. But my parents constantly make fun of the name saying that they are going to tell the child it sounds like a disease. EXCUSE ME!?! Don't ever talk about my child that way unless you truly don't ever want to see him or her. They are getting to the point that they are unbareable to be around. They won't let me be my own parent. My mother always says, "women have done it for centuries quit worrying" wel I'm sorry but I am a first time mom and don't want to be a royal pain in the ass like you were. I want my child to have a good childhood and family and if that means that you think you can call my child a disease because you don't like the name well then you can just suck it. I have no idea what to do about this and I feel like I'm going to lose my mind dealing with them.
