Pregnant vs mom

I’m 6 months pregnant.. and So my mom is the jealous mom.. she gets jealous when my MIL is involved in my pregnancy in any shape or form. Honestly, not just jealous over my MIL, over all my in laws. She got upset when I told her my SIL was pregnant and I was happy bc my unborn daughter would have a cousin very close to her age. Her response was “she will have abby” who’s my little sister who is 9. Which, she’s not wrong! She will have her aunt! But idk, I was excited that she’d have a buddy that’s only a few months apart. When I sent her a picture of some clothes I got my daughter, her response was “well, guess I have shit to return” or when I showed her the baby’s crib and changing table, she told me to stop buying things because I’m having a baby shower. But the thing is, I wanna buy all her furniture because I wanna design the nursery. So last night, I told my FIL and MIL when the baby shower was, April 3rd. I’m due may 2nd. My FIL told me that might be too close to my due date. So I went home, thought about it.. and myself and fiancé agreed that it might be too close to the due date and decided to move it to march 19th. So obviously I messaged everyone that is involved in helping plan the babyshower that we moved it, everyone’s response was “oh okay” or just anything along the lines of normal. My moms response was “why? Shouldn't you be talking to me about this before you change things lol!! I’m hosting it”.. well, I never told her she was hosting it.. my FIL and MIL and my father are also involved in planning it. My FIL is helping pick out the venue, and helping getting the food and renting the tables and chairs. My MIL and mom where gonna help with the decorations, and my father is just helping with anything else. He just wants to be involved in his first grandchild’s babyshower. They all wanna be, they’re all excited. So I specifically didn’t have one host. But she just got so mad! We spent all day fighting about it. She kept saying she didn’t like the date! So I told her I’d do march 26th just to keep her happy. Idk why doing march 26th makes her happy? Maybe because it makes her feel like she picked the date? When I first told her I picked April 3rd, her response was “who picked that date!” I told her I did, because my grandpa who passed away two years ago, that’s his bday. So all of this is just half of what she’s said to me and would fight me on.
