I do think it's difficult for some people to accept that our children are absolutely separate people who may well be utterly different from us. I don't enjoy playing video games even though I can play them and sometimes play with one of my sons if he's having a bad day and feeling down, because it means a lot to him. My DH loses himself in a videogame given the opportunity the same way I lose myself in a good book - why don't/ can't I? Am I missing out?
I do think that adult type reading doesn't necessarily "kick in" until a certain fairly late stage of brain development. Being able to read functionally is only a part of the skill. It's not possible to "lose" yourself in a book if you're reading every word laboriously, and reading a school book aloud is totally different to listening to a good reader read to you, which is again utterly different from reading silently to yourself - and that isn't one experience either as a fully developed adult reader absorbing fiction for pleasure is having an experience with no meaningful similarity to the same adult reading a dry technical text, or a child reading one word at a time in a linear way even if silently.
My eldest loves to read now at 16 but I read to her until she was 13. She read some children's and teen fiction to herself but not much. Then suddenly at 13 she started to read the Brontës and Jane Austen at astonishing speed and no longer wanted to be read to 😱 It was a staggering developmental leap really, from the occasional Jaquelin Wilson, to The Hunger Games and Maze Runner but really only reading perhaps four or five books per year, to suddenly reading Pride and Prejudice and Wuthering Heights and Emma all in one week and burning through my bookshelves, planning trips specifically to bookshops etc.
My 10 year old is dyslexic and yet has always liked to read, but for him it fulfills a need as he has problems sleeping and worries about not being able to sleep, and knowing that he has books is a security blanket, and reading helps him quiet his busy mind. He read comic type books (Captain Underpants, Dog Man, Hilo and we had a Beano subscription) for the longest time but more recently he reads on in Rick Riordan books I read to him at bedtime.
My 14 year old still doesn't read for pleasure really but he motors his way through a set reading list for extra credit for school to bring his grades up - he has to take comprehension tests on each book which makes it a chore and I'm on the fence about whether I think this is good as at least he reads or bad because it's potentially going to put him off coming to reading for pleasure in his own time one day.
My DH reads for pleasure sporadically - he'll get into a series or author and read one book after another for a few weeks or months then suddenly stop and not pick up a book again for a year... He says he never read a book voluntarily until his early 20s
In other words everyone is different, she isn't you and should be different to you. Don't push her - she might come to reading for pleasure all of a sudden much later than you expect.
