Am I being childish not wanting to share my baby shower?

So long story short my aunt and I are due one month apart. This is my first baby and her third. When I announced my pregnancy there was no congratulations, or even acknowledgement of my pregnancy which I’m assuming may be because she was actively trying for a third while my pregnancy was a surprise. Now that she’s announced it’s become sort of the understanding that part of my baby shower be about both her and I. As in lots of photos, celebrating her as well, and generally just sharing the spotlight in a way that I don’t necessarily want. She has a tendency to make things about her and her kids even when they’re not at all. Mother’s Day she didn’t acknowledge or celebrate my mom at all but wanted to be showered in praise and gifts and dominated the whole day even though there were multiple mothers present.

This is my first and I just kinda want my baby shower to just be about my baby and me. If she wants to have a third baby shower she should but I think my baby shower is not the place for her to be the center of attention and I don’t think I should be expected to share that limelight on that day.
