Okay rant time

So my mom and her friend are planning my baby shower and is making me make a list of friends I want to invite. She ends up messaging me saying 70 people are invited so far and she wants to keep it under 100. I don't know who all she invited and most of them are probably her friends. How do I tell her that it's not fair without her getting pissed off and end up not throwing me one? Not to mention, most of my friends have kids and I pretty much have to tell them to leave their kids at home...I can't do that! I want them there
