overbearing MIL

I meet my MIL once every few weeks and every single time she will snide or make unpleasant remarks about my choices and my pregnancy changes. She recently asked about my weight gained and laughed, saying that she and her daughter didn’t gain so much during their own pregnancies. 😞 I told her that my gynae has no issue with my weight gain. So far she also made noise about me doing amnio, taking covid vaccine and wanting to take epidural during delivery. She has never once asked about my choice and just lectures about what she thinks is right. My husband is apologetic and tries to mediate in front of her but it still affects me. I’m learning to cope with her unnecessary comments, takes a few days to get over each time but i know it’s just going to be more to come, especially after I deliver. She has no filter and won’t change even after we feedback to her. Any tips on how to manage/cope better? #advicepls
