Mother in law acting weird..

Destiny

My mother in law keeps referring to my baby as her baby... she’s constantly asking me “oh hows my baby doing” “my baby’s going to be so cute” “I’m so excited to meet my baby” it’s making me so uncomfortable... Am I overreacting? She’s been doing this my entire pregnancy. She’s even referred to her as her daughter. I corrected her and she looked at me and turned and walked the other way. She’s constantly overstepping boundaries and touching me without asking and every time I ask her to stop she says “I’m just trying to feel my baby kick. I have two weeks left until my due date and last I spoke to her she was livid my fiancé and I said no one is seeing the baby after we have her for a bit because we’re first time parents, bonding, and I’ll be recovering. She told me I will not be keeping her baby from her. I don’t know what to do anymore she’s constantly making me and my fiance uncomfortable with her behavior. Anyone having the same problem?
