mother in law wants to basically take my baby

So my boyfriends mother has already got her own set of everything!! And we haven't even got half the stuff she has yet. We live 3 blocks from her but she's acting like the baby will live with her. She already thinks she's going to be in the delivery room not even thinking about my mom being there before her. She also talks about the first nights of the baby home really acting like it's with her at her house saying she's going to be up all night with the baby. I don't feel any good energy coming from her I feel like she's just trying to take the baby from us. I'm actually scared because I see in her eyes she wants this baby . NEED HELP
