Surprise baby shower?

lizztheo

I think MIL is trying to throw me a surprise baby shower. She has not mentioned a word about wanting to throw one but she's made a Facebook event for "save the date" with a photo of me and my husband, and Facebook invited about 50 people. I am a bit upset because my mother wanted to throw a shower for me and I'm okay with having two but I feel like I got no say in this. What about friends I'd like to invite? She got mad about my bridal shower because all her friends weren't invited (the person throwing it wanted to keep it small around 20 people--her two best friends we did invite, didn't even show up and MIL and SILs were all late). Is she just trying to one up my mother? How do I approach her? Help!
