Can I be wrong?

So I am having my second baby in November. With my first I had my mom and sister with me apart from SO in the labor room. Well my mom was annoying that day to me she's the type to post every detail on Facebook while I'm more private and just might post a baby pic later and it bothered me having her stuck on her fone also when your hungry and can't eat 😑 but they decide to eat in your room cornuts of all things. Noisy!!! Anywho my mom and I have become estranged in the last year and a half. We don't call each other we only talk at any family events when we see each other but it's awkward. So my thing is will I be wrong if I don't let my mom know I am in labor or my sister I just feel it would be awkward. And my sister and I get along fine but she's a mommas girl and she will start with her stuff if I call her and not my mom. Our issues cannot be easily resolved we tried it once and we got no where. But I just don't want the day to come and feel like I need them there and I'll regret it. Any kind word are needed here !! Thank you ladies
