Am i being to picky???

Sylvia
Hello ladies!!! I have a little issue and I want some advice from some soon to moms just to make sure i am not being a Mom-zilla. So the attached picture is what i put out on facebook just to let others know that I want to be the first to announce my son is born. (I have 2 days left till i am induced) and my mother is throwing the biggest fit!!! My SO parents live in Alaska and we live in Kentucky so i just asked my mom to wait till at least we talk to them and made them aware of his birth but she is now threatening not to even come to the hospital. Am I just being picky or is ok that request a private moment with my new baby?
