Breastfeeding In-laws

Living with my in-laws for 1-1/2 more months. My mother-in-law has not been supportive at all of my breastfeeding. We had a 30-minute discussion a few days before we delivered about how breastfeeding works and privacy needs and hunger cues. (MIL did not breastfeed.) And it's like she completely forgot our conversation and she keeps bugging me to give our little one a pacifier and a bottle so she can feed her and hold her longer. I currently enjoy spending all this time with my baby and being her comfort. She's constantly trying to come in our room and wake the baby. She's been great about being on a schedule and when she gets woken up she will cluster feed for hours.
Why must my MIL be so difficult...
