Sadly this is about my own mother

I’m supposed to be on bed rest because I’m a high risk pregnancy and my mom expects me to walk down the street and bring my daughter to her house and pick her up. My daughter missed my mom aka her grandma and my little siblings so I decided to just stay there so she could hangout and my mom has all the drinks in the basement. I asked my mom to go down to the basement to get me a drink and she says “NO I have my daughter (3 years old) in my lap and go do it yourself!” Am I the asshole for going home and telling everyone I’m not going back over there until after the pregnancy because of her not understanding what bed rest means and telling them my daughter won’t be going over there as much because she will refuse to bring my daughter home unless I pick her up when they all can just come to my house because it’s not that far away? I feel I already did too much because I shouldn’t have to go down two flights of stairs to exit my house to bring my daughter there in the first place and she’s too lazy to grab a drink? I also told her if she dares to say I’m lazy for following doctors orders she won’t see my daughter or son when he’s born because she clearly doesn’t care about her unborn son in the slightest and is just a lazy old coot
