Really need other mom’s opinions on this(this will be a bit long but need help)

So I’m 35 weeks pregnant with our first child. I am pregnant with a girl and we wanted to try and take care of her completely by ourselves when she is a newborn on the first days/weeks. We were offered help by only one person but it’s someone we don’t get along with and don’t want help from. It’s my MIL.. A little backstory.. My MIL had 4 boys and was obsessed with having a girl her whole life (a fantasy and severe gender disappointment), it’s to the point she just ended up being a bad mother to her boys because I guess they just weren’t enough and they were failed attempts at having a girl. She is younger and very bitchy. Her fantasy of a girl is so severe that she feels like my unborn baby is the girl she never had(this is her first ever grandchild).. She is being extremely weird about it... She said she wanted my girl to call her “Mama”. My husband never got along with her literally EVER. He has always been very distant from her and they get into arguments 24/7 because she was always a bad mother to him. She is the type of woman that prefers to spend money on her nails, expensive clothes and men;then leaves her kids with nothing. Well now getting to the present.. She has been bugging us so badly on how she wants to be there with the girl taking care of her and making us feel like we could never do it by ourselves. Other people are telling us to let her take care of my baby because “I won’t even want to be near my baby”... She said we could let the baby fall when we are changing her diaper.. 😐What does that even mean?? She also pressures on breastfeeding (she will make me whip out my tits and pressure me to breast feed) I know it has many benefits but some women just can’t do it.. (She will make be very uncomfortable) When we told her we wanted to do it ourselves she says “Why would you ruin my dream?” What?????! She also said newborns need a bath everyday which I haven’t heard of... I just think she wants to fulfill her fantasy. Would you guys take the help anyways? I’ve never had a baby so I don’t even know.. My husband really doesn’t want her help. What would you guys do in my situation?? Do you guys think we can both do it alone or do you think I should just let her? (everyone is making it seem like it wouldn’t even be possible by ourselves)
