See, I completely get where you’re coming from, especially because I am personally child free by choice and have no interest in being a mum.
However, Alice DID push the narrative of being a single mum a lot. She wrote a book about it. A lot of her online content and ads involved her children. She wasn’t a full blown mummy blogger, but she was definitely close to that, and being a parent seemed to be a significant part of what she put online. Then it just all went away one day, without explanation.
That’s what annoys me, and that’s what I find baffling. I have a friend who was utterly confused by Alice’s disappearing kids - she followed Alice because she loved seeing a single mum she could relate to. Fab for Alice that she can just check out of her major responsibility as a parent, but not every mother can. I’m aware men do it all the time so I don’t want to judge too harshly, but I still find it utterly strange to not address it at all.
