Ugh mothers!

Okay so my mom has invited herself to my ultrasound today, which I'm fine with, besides the fact that she's demanding to be right there when my boyfriend and I find out our baby's gender. We already decided that we wanted to find out alone and surprise everyone with some gender reveal photos in a few days...I would be okay with her finding out with us if I knew she wouldn't go and tell everyone right away, like she did when I first told her I'm pregnant. She made me tell certain family members right away and then went and told all of her friends without bothering to consider my feelings about it.
