Would you let your babies grandma take her/him for a weekend? ( read discription before answering!! )

So, i am 32 weeks pregnant and I was with my boyfriends family the other day at a cook out, we were all talking and his mother asked me “ are you going to be breastfeeding “ and i replied “ haha no “ and she said “ well i guess thats good so i can start taking her sooner. “ She has already voiced that she wants to be able to take her once or twice a month for a weekend, she lives about 45 minutes- 1 hour away from us. She wants to start when the baby is still only 1-2 months old, which im just not comfortable with. I don’t know when i’ll ever be comfortable with her taking the baby for a weekend, once or twice a month. I don’t know her that well, my boyfriend has told me she was a terrible mother growing up ( he lived with his dad ) but now she has their younger sister every other week, so i guess she became better but i dont know. What would you do in this situation??
