MIL drama gets worse when pregnant

My MIL is not my cup of tea. Although we are both Christians she hides behind her faith like it allows her to judge and say things that are not her place. When I've been pregnant my tolerance lowers and also her passive aggressive statements get worse. I can't change the woman and I'm allowing her more time with our children and also try my best to accommodate her wims but I'm emotionally getting exhausted. Maybe three times a year I ask for her help with watching the kids she begs to do it this. Thie week She had it scheduled for over a month to watch my kids for one hour so I could make it to a specialist appointment. The day before she asks if she can cancel so she can schedule an appointment with her doctor for a routine followup with a primary. I work from home and have two kids and pregnant I can't just reschedule my appointments with specialists. She is retired and does nothing. I'm not going to ask her to watch the kids again this pregnancy it is far too stressful and her calling canceling and being passive aggressive with how she talks to me is ubcalled for. She keeps asking if she can have my FIL watch the kids who is 82 deaf and can hardly walk we keep saying no. Recently it was judgment for throwing my kids a birthday party and she keeps talking about the quantity of gifts (chalk, bubbles, books.) How she didn't get the kids gifts and how they had too much. I'm pregnant and really high risk so I'm trying to lower my stress. We took her out to eat Monday and she asked for a to go box two bites into our dinner because she didn't like how our two boys couldn't sit still in a family restaurant when they were bothering no one but kept switching places to sit with eachother. Our kids have only eaten out 3 times in their lives so we are trying to teach them they were not naughty just talkative. She wants to take the kids for their first sleep over at her home and I'm so anxious about it for next weekend. I get tired of being told my kids are naughty but she wants to be around them. I get emotionally drained by comments "They have enough stuff." Or gifting me a blank card for mothers day that just says "your a busy mom" nothing else on it? Or she purposely does things that are bothersome like we've asked family not to gift the kids anymore stuffed animals they just don't get played with. This week she brought over her stuffed animals from her home and left them all at my home on purpose. It's a passive aggressive move that is unnecessary. I've gone no contact with her in the past and for 2 years she wasn't allowed in our home for her behavior. My husband has sat her down and told her to knock it off but she doesn't. I'm trying to lower my stress and the more time she is around me the more worked up I get. I legit can only control myself and how I exchange communication but I'm ready to just excuse myself from talking to her at this point again until the baby is born as it effects me. Her behavior hasn't always been harmless and she's got aggressive physically with me so I really have no issues with just stop talking to her when she gets to be too much. My husband is a good son to her but she has issues with abandonment and he is her only child so she is clingy and he isn't the most understanding of that with her. I'm not sure how to get through the summer with her and my hormones. I wish to have a good relationship with everyone and have realized I don't need one with her just minimal for the kids sake. She found out the gender of my newest pregnancy by accident from my husband refering to baby as a boy. At our gender reveal she then told people what it was and made my family hurt thinking she was specially told. Then made a big deal about how I didn't give her granddaughters. When she knew our last baby was a girl I lost that pregnancy and my husband is having a lot of issues with grief. I've got great family and other great in-laws I'm really just don't know what to do about her anymore. Everyone knows its a bad relationship from her snubbing me in public or by me avoiding any conversation about her. I am trying to lower my stress and yesterday was just hard with her and I'm not going to ask her to watch the kids again but also how do I manage my anxiety around her?
