AITA for not involving my childfree sister in my pregnancy?

Yeah. I actually have a ton of sympathy for the childfree sister here, as it sounds much more like she's just super uncomfortable with kids and doesn't know how to connect with them, not really like she hates them or doesn't care about them. It also sounds like the oldest sister disincludes her pretty thoroughly from her life, which makes me wonder if the youngest sister grew up without much emotional intimacy. It makes whole set of behaviors kind of make sense, anyway. I'm not sure it makes the older sisters the assholes, but I'd be interested to hear what efforts, if any, they made to help the younger sister feel connected with them and their families.
