Probably get hate for this with it being Mumsnet but I am child free, last one of my friends. Someone who used to be my best friend is due her second child soon. In the last few years whenever I have seen her, there is no other conversation other than kids. We meet up in a group of 4 often and the entire conversation is about kids. Someone will ask about my life and she shows no interest and somehow diverts the conversation back to herself/kids. When I see my other friends individually we surprisingly have other things to talk about. Even on social media, every single story is about her child or pregnancy. AIBU to think this isn't normal?
