I wanted to say, "That old baba must be some special kind of dumb because she didn't believe her daughter despite there's even a clear report from the doctor. The author kinda overdid with the characterization there."
But when I think again, we live in a world where flat earthers and anti-vaxxers exist, plus people who refused to wear mask despite there is covid-19 pandemic, so I guess the author doesn't really far from reality here.
