No one is rsvping to my baby shower...

I sent out 50 invitations 45 of them told me they were coming but no one but family is rsvping to my mom for the SAME REASON. It’s because they say it gives them anxiety to text someone they don’t know like they don’t know what to say. The will rsvp to me and not my mom. I think this is so so annoying. I even sent them a template on what to say nobody is doing it. It is upsetting my mom cause she has no clue who is coming. She wanted to keep track and have it all organized. I’m just so upset my friends can’t grow up and text my mom to say hey i’m coming.
