Mother in law doesn’t know boundaries

My boyfriends mother keeps trying to wiggle her way in the middle of me and my boyfriends life so bad ! I’m currently 19 weeks pregnant, and still don’t know the gender of our baby. At week 9 we came over to visit her and she pulls out these bags of heavily used baby clothes and tells us to take them. At this point we have no idea whether we’re having a boy or girl and these bags are filled with both boy and girl clothes. I pretended to act happy but in my mind I was upset. This is our first baby and I refuse to put my baby in these super worn clothes. Not that I have anything against thrift store clothes or hand me downs but I was still appreciative and said Thankyou but told her she should keep them for now until we figure out the gender.She then starts telling me that a few years ago she gave a used baby rocker to her sister for her baby to use and now her baby grew out of it so she told her sister that she wanted it back and that she would go all the way to Mexico to pick it up for me to let my baby use!! Ughhh Heres more ... Couple weeks later she gets this “bright” idea that she wants us to move out of OUR apartment and find a house with her, her husband and 3 other children. Every chance she gets she has to try to convince her son , saying that it would be better for me because I’m going to need the help to go to my doctor appointments while he’s at work and “what if I go into labor we want to be close to take you”. I definitely appreciate the thought and help but I can take myself to my own appointments anyways I’m only 19 weeks pregnant right now. The last thing I want is to move with his family and be stuck living in this crowded home when we have a family of our own now. My boyfriend really liked the idea of moving with them for a while so he can save money for a few months and just move to our own place a month before I give birth but it’s not that easy. We cannot guarantee that we will even find a place around that time. Imagine if we couldn’t I would be PISSED to bring my baby home to a rented out room where I do not feel comfortable! Another thing she constantly keeps calling me telling me she can take me to these classes where if you attend them you get free items.(car seats, strollers, etc ...)free things are nice but I don’t want to attend these classes just for these free gifts . It’s way too early and I wouldn’t even know which color to chose when it comes to it . Pink or blue? So I’ve been telling her no it’s okay when we have a baby shower we can figure out everything else we are going to need for the baby if anything is missing. Me declining is starting to make me and my boyfriend fight because she insists and insists way too much and she’s putting all this stuff into his head and him being a first time father , he’s letting her tell him what to do... what she thinks is right and wrong. Almost every week she is calling us and telling us that she would pay for us to find out the baby’s gender early , but the trick is she wants to be in the room and be the first to hear . I specifically want it to be a special moment and just want it to be me and my boyfriend but like I said she never gives up on asking ! I’m terrified for when I give birth because I don’t want anyone to be with me in the room besides my boyfriend but I feel like she’s going to try everything in her power to be selfish and ignore my wishes that day. Someone bring help 😞😭
