Should I have two showers (read for details)

Looking for advice. My stepmother has a rather large family. Like she would be inviting at least 20 women to my baby shower kind of big. We are planning a shower for late April, so weather is questionable. Also, my mother and stepmother are not exactly buddies.

My stepmother suggested I have two showers. Basically one for her/my dads side and then one for my in-laws and my mom. She proposed it as a way to not have he event(s) be too big and difficult to arrange. I think another part of it though is that she doesn’t wanna have to spend time around my mom. I find the whole thing ridiculous because my parents divorced before I can even remember and my father was remarried when I was 8. So it’s been long enough IMO, but whatever.

I’m worried about the two showers cuz of obviously having to schedule, attend, and deal with two showers. Also, I kinda wanted this to be the thing that forced them to kind of get over it and be ok with being near each other. I don’t plan to do 2 birthdays etc for my child’s whole life, so it’s going to have to get figured out at some point soon.

So, what should I do?

Have two showers so it’s (hopefully) just simpler and smaller and I they don’t have to be uncomfortable

Stick to one so they can adjust and also because my schedule is going to be pretty full as it is. Also, maybe kinda awkward to have it separated like that??
