] It is interesting that we don't get to see her doting on Harry. We don't even hear her described as a doting mother who spoils her child, like Lady Middleton is described. Does she spoil him and coddle him? Or does she ignore him and leave him to the care of nannies?

IMHO, Fanny might be a good and attentive mother to Harry. But that is because she has been always self-interested toward her needs and those people she wants to take care of. She actually seems to be more interested in taking care of herself and Harry, than that of John. Much like another JA character, she is interested in only the welfare of her family circle and selfish and mean to everyone outside of it. Only she is probably unredemptive.
