My grandma is a NIGHTMARE she keeps fat shaming me

Let me start off by saying she has always been like this with everyone and I just need to rant . My grandma is 74 years old but looks younger than she really is. She is over protective of my 4 year old and baby’s her so much. She lives with my mom and I don’t live with them but im here temporarily as I’m getting my new apartment fixed up and painted. A few years ago I did live with them and she once was holding my daughter who was a few months old back then and said “I am more of a mother to to u than your own mother” which really made me flip out as she said it in front of my face. I completely lost it and told her to never say that again and told me I’ll be a “drug addict and a loser mother” (I’ve never done drugs so what the fuck?)

This time around she’s been commenting about my weight and how the baby is going to be so big and how I need to stop eating and basically fat shaming me and I’m getting soooo annoyed. She says things like when I’m getting water from the kitchen she will say “omg ur eating again?” , last week I told her goodnight as I was heading up stairs and told me “what are u doing here eating again? Didn’t u just eat hahaha” . Every time she says these things I am not even eating it really bothers me . She’s a very defensive person. I cannot tell her to stop that I don’t like it or she will turn it around on me and cause a huge argument which I’d rather avoid.

So today I simply ask my mom “oh what are u eating ?” And my mom responds and I say “ohh ok cool” I was about to walk away and my grandmother jumps into the conversation and says “hahah she’s gunna want to eat that next after she just ate” she got on my last nerve that I mocked her laugh and said “haha how about u be quiet im getting sick of ur comments” and I walked away. I know better than to disrespect my elders but I feel like she keeps picking on me when I have not done anything to her . Also I have only gained 11pounds this pregnancy and baby is measuring small so it frustrates me.

I originally was going to let her be in the delivery room this time around for my second baby but after being here and her rude ass comments I am no longer letting her be in there as I feel she doesn’t deserve to be in there. SORRY NOT SORRY.
