Me and my boyfriends mom have always got along amazingly before I got pregnant. She pissed me off during my pregnancy. She'd tell my boyfriend that my vitamins are supposed to keep me energized and I napped to much all this bs. When I told him that's not true she said i was calling her a liar and tried turning him against me. Then which I believe is completely selfish downed my decision on breastfeeding because she wouldn't be able to feed the baby only I could even though I decided to breastfeed because it's the healthier option she acted jealous. I ended up brushing it off and didn't bring it up the rest of my pregnancy so we was fine again until now. She lives at my boyfriends house because she can't afford anything on her disability check. This past week we went to stay with my boyfriend. She completely took control. My baby is 2 weeks and she gave her baby food after being told no. I had to stay up all night because she had a stomach ache afterwards. Then she guilted my boyfriend into letting my daughter stay the night in her room even after we told her we wasnt comfortable because she has a tendency of passing out. Not even 15 minutes of leaving her in there I heard my daughter crying louder than I have ever. She doesn't cry often at all and for her to be that loud alarmed me so I sent my boyfriend to check on her. My daughters upper body was off the bed and her butt was held on by his mom as she was passed out. I took my daughter away and she started saying some pretty upsetting stuff towards me trying to turn my boyfriend against me. Then not even asking if I or my boyfriend was ok with it she gave my daughter tea. I was so upset because I had personal reasons I didn't want her to have it. I told my boyfriend he understood. The next time she went to give it to her he told her not to and she continued doing it while being told no. Then when my boyfriend went and told her to back off (he said it much nicer than I would have) she kept saying we wasn't letting her be a grandma and that we thought she was stupid and a bunch of stuff once again against me. Then asked to help me give my daughter her first actual bath. Took completely over I didn't get to do a single thing. I wanted to completely cry because that's a moment I wanted as a first time mom. Honestly I don't know what to do and don't want to go back over there but that wouldn't be fair to my boyfriend or my daughter Thoughts on what I could/should do?
