Does anyone experience this with your mother and kids?

My mother gets very sour and jealous when hen my two little ones spend the weekend at the their other grandparents house I’m over it. When my toddler comes home and throws her usual tantrum she will yell “where are you learning this behaviour from?” As it to say no one teaches her nothing at their place. Even when I tell them they’ll be there for the weekend she will say “ok” really flatly and nothing else. When my other little one was in hospital and my toddler was at their other grandparents house i asked if they could have her while I was at the hospital because she was already there and it was fine I told mum not to worry she was alright just to leave her there and then she calls my older sister from work and tells her to go and pick her up even after me telling her to leave her there she’s fine. Luckily I called my sister to tell her not too and she didn’t mind but I was so furious at my mother when my kids are around she just screams about the mess they make. Me and my siblings only grew up with my dads side and not hers and she always says how she wished we had met her family but for me luckily this ain’t the case I’m lucky to have two loving families for my children to enjoy I always have to remind her that we have two families not just her that’s why I did understand why she doesn’t get it or she gets upset but this really grinds my gears. What should I do?
