Reading about how unloved Jane was as a child I find it amazing she didn't turn out as twisted as Mrs Reed accuses her of being. I can only think that the affection that Bessie shows her does mitigate the lack of affection and the outright cruelty of her aunt and cousins. Or is a wonderful demonstration of how resilient children really are.
The detail that stood out most in the first chapters was about Jane's doll:
To this crib I always took my doll; human beings must always love something, and in the dearth of worthier objects of my affection, I contrived to find a pleasure in loving and cherishing a faded graven image, shabby as a miniature scarecrow. It puzzles me now to remember with what absurd sincerity I doated on this little toy, half fancying it alive and capable of sensation. I could not sleep unless it was folded in my nightgown; and when it lay there, safe and warm, I was comparatively happy, believing it to be happy likewise.I think what strikes me most is how puzzled the adult Jane is at the memory. I suppose in part her reaction seems odd because it's such a contrast with a Christmas picture book I've been reading over and over again to Isabella, The Story of Holly and Ivy by Rumer Godden, which is the tale of a little orphan girl who falls in love with a doll. And of the doll who falls in love with the girl. Godden takes it for granted that a doll is a worthy object of affection for an orphan child. Though she also provides Ivy with an adoptive family at the end of the story, so I suppose the doll is necessary but not sufficient. Godden has written quite a few doll tales, all of them are at least in part told from the dolls' point of view.
Jane on the other hand seems to feel some distaste for her childish affection for the doll. I can't tell if it's just that it was meant to be a rather hideous and pathetic doll or if it's a more general feeling of revulsion for that much emotion being lavished on an object rather than a person. I suspect the latter though since she refers to it as a "graven image". We're meant to see it as a sort of idolatry.
