This is how real children work. Anne's probably the most realistic character of the week in the show if anything, the author getting over his issue in one episode is way sillier. Kids are far more intuitive than most people seem to think. If you're not willing to take my word, just do any research at all on child studies.
Kids operate on intuition because they lack knowledge. If you look at the situation from Anne's perspective, there's no reason at all that a life-like doll shouldn't exist. She's been told that a doll is coming to her house, her initial skepticism gave way when the doll acted as it was expected to and revealed that it had a mechanical body. She thought Violet was a doll because it was the logical thing to think.
On the end of her mother dying, all the clues are similarly there. Her information on the world is incomplete but she can piece together that her mother is slowly losing function. Most children become aware of the concept of death pretty quickly just because it's inevitable in every culture, but Anne is being raised in a post-war era. It's not an inconsistency in her character, it's the opposite, she comes to both conclusions the same way.
Common sense has to be thrown out because trying to look at the situation that way is exactly what makes someone become illogical and ignore what's actually written, and even real world information that isn't regularly spread.
