Not letting people in my family I don’t like see my baby

I need a what would you do/go about it opinion from somebody. I’m 7 months pregnant and have stressed from time to time during my pregnancy letting people in my family I really do not like see my baby when she’s born. These specific people are my siblings. Half siblings. I have never found a interest an any of them nor have had the best relationship/any relationship at all. Yet they all show interest in seeing the baby and I’m just not for it. It’s more of a they like me more than I like them type of situation. And yes I have my reasons for not liking them, it’s been this way for years. I’m still nice when I come around and it kills me if I’m being 100% honest but when it goes as far as being in my kids life idk about all that. I mean I shouldn’t have to feel obligated to let them in her life, right? My only annoyance here is I know someone in the family is going to try to make me feel bad about it. I do not want to hear it from them. She’s my baby and I decide who she is around and influenced by. I don’t really think I’m doing anything wrong here if anything I’m saving my child from the burden of annoyance from these people and if that makes me a bitch then I guess so be it but honestly if you were in my situation what would you do?
