Mil Sil baby shower drama.

So before I had drama with them and my gender reveal party. Now more drama with the baby shower. So my sister in law who has 4 kids told me and my boyfriend we should put our baby up for adoption because she’s jealous that their side of the family is showering us with support and gifts and she burned bridges with them a long time ago. My mil already took one of our gifts a baby swing that we got early from someone and gave it “to borrow” to my sil since she just had a baby and ours isn’t born yet. Now my mil keeps asking if sil is invited and we keep saying no. And she’s like well Can I bring her kids and we’re like no. We love the kids but why bring four small children to a baby shower when they live and hour away and it’s only for 3 hours. Now she’s guilting us and saying well she keeps asking when the shower is and I guess I just won’t tell her. I’m like tell her whatever you want she’s still not invited. Why would she wanna come somewhere that’s for our baby when she doesn’t even want us to have the baby. Now I’m thinking of not inviting my mil either because of the minipulation and disregard for our baby and our special celebration.
