Thank you everyone for all the great responses, you have given me a lot to think about.
To clarify- it's not just me, I have my husband, my other child, my sister is coming along too (she is Christian, not Muslim), and other visiting nearby family (we live in Quebec and a baby is celebrated with wine/beer without question), so it's a bit of balance trying to accommodate all.
My mother is not the kind to complain or speak up if she is bothered by it, which is why I'd like to ask everyone. She is here for a week, on her own expense (something she really can't afford much), to help me out with my new baby, do laundry, cleaning, etc. so it's not just a few dinners here and there, but wanting to make sure I can show her how much I appreciate her visit/help, since I have other kids she will be watching too.
As for being pregnant, I was due yesterday, and there is no room for any food in my stomach anymore LOL, I am barely eating at this point. It is balancing my husband/his family's desire for traditional Quebecois pork cuisine/alcohol with my mother.
