My mom always seems to say negative things to me

Okay so I'm at a loss on what to do about my mom. I'm 21, married and I have a 7 month old daughter whom my mom loves. I feel like no matter what I do, what I wear, what I say it's always wrong. I feel like everything she says to me is a snarky unnecessary comment.

Here's a couple examples of her comments:

My mother in law came up to visit my daughter because she wasnt able to spend much time with her when she was born because we were moving for my husband's job, well she wanted to explore the city and eat at some specific restaurants that's were famous and they were definitely on the pricey end 😬😬 well I sent my mom a picture of some crab legs and her response was "Must be nice to have so much extra $$ to eat awesome food... I'm over here on Ramon LOL" 🙄🤦‍♀️ my mother doesnt eat ramen, like EVER, my family had 2 giant ass Christmas dinners one included smoked duck, they have smoked brisket multiple times a month, smoked chicken, they randomly have cheese sample tables, my grandpa makes fresh homemade seafood gumbo/Jumbalia etc so they are not eating poorly she just wanted to make an ass comment.

Another example is I'm starting to plan my daughters first birthday party, my husband's parents live in Florida and my parents live in PA (we are on the west coast now for my husband's job) but they are going to Disney in June for a family trip. My mom and I were trying to pick a day that didnt disrupt their plans but fit in my Mother/Father in laws schedules. So I told her i didnt want to have my daughters party on Thursday because i didnt want my father in law to drive an hour after he got off work, stay however late at the party and then have to turn around and drive an hour+ back to his house to be up at 5am for work, that maybe a friday could work better and her response was "If he cant drive an hour for the babys birthday party that's pretty selfish, it's not about him it's about your daughter." Like he has to work? How is it selfish to work all day get off at 4 or 5pm and possibly not wanting to drive and not enjoy the party when we can have it the next day? He has already said that he would call off on Friday to come and have the whole day with her.

The last example I'm gonna give is about my outfits. I'm 5'7 120lbs I am literally all legs, when I was pregnant I was wearing a black romper that was shorts and I posted a picture of my husband and I at the movies on facebook and she commented asking where my pants were (insinuating it was too short), I told her it was shorts so there arent any pants and she said "Oh it's short all right"....I have giant ass boobs as well (34G rn because I'm breastfeeding, but regularly I'm a 34DDD) so it's hard to find shirts that arent going to show a little bit of cleavage she will comment on EVERY SINGLE ONE, saying I must be insecure, how it's better to be noticed for my intelligence as opposed to my body, how I'm married with a baby so I shouldnt be dressing a certain way etc.

So basically I'm just at a loss of what to do. I dont know why she acts like this everytime we talk or everytime I post something. I want her to be a part of my daughters life and all but I'm to the point where its obnoxious and annoying af. Is there a way to get someone like this to see they are lowkey constantly bullying and belittling me? Any ideas why tf she does it? I really just need some advice 🤦‍♀️ also I'm sorry this got so long and if you need anymore insight or have questions about anything I'll be happy to answer I just need to know how to either address it or fix it. TIA
