What would you do?

Me and my mother have never really gotten along and until I told her I was expecting she never bothered to check on me or really attempt to have a relationship. Now she's always asking how her baby is and refers to my unborn son as hers she gone as far as saying I'm only a vessel for this baby and once hes here I do not matter . I wanted her to be involved in his life but the way she has been acting has made me question alot . I've told her my plans to have a private delivery and she lost her mind saying I was robbing her of her rights to her baby .I've told her it's my baby but I dont think she's getting it what should I do
