Mother in law is creeping me out!!

Ok so, my husband and I are expecting our first baby. This baby is also my mother-in-law's first grandchild. We've always have gotten along... But now that im pregnant, she is starting to do and say some off the wall stuff and it's starting to freak me out a little. First it started with her saying she is going to be pretty much living with us for the first month or so after baby is here... No, she did not ask if we would like her to do this... Just that she fully intends on doing this. 😳😳 I totally appropriate her wanting to help, but "living with us" is not necessary... Is it?? Second, she thinks she has a say in what we name the baby. She wants family names... Not from my family of course, but just her family. My husband picked a family name for a boy way before we were even pregnant, but I picked an original for the girl and she WILL NOT let it go! My husband has even told her it's not her decision and that she needs to stop being so disrespectful about it and she still wont stop!! And last but certainly not least, this is the one that sent me over the edge and had me decide to post this rant... She keeps refering to my baby as "our baby" like she has some kind of claim to him/her! She says things like "I can't wait for our baby to be here!" Or "our little ones getting big in there, arent they?" Or how about "I cant wait to spoil my baby when they're finally here"... Am I just being a crazy pregnant lady and reading too much into this? Or do I have a real case to tell her to stop being a crazy person?? Oh and a side note, she pulls most of this BS when my huband isnt around so he thinks I'm "just taking it the wrong way." Is he right? Maybe its the hormones but I feel like shes crossing some lines here.
