We've got The Sheep Pig (older brother had it) and it's on her shelf now! My husband went to the charity bookshop today and picked up some of the recommendations here, so again, thanks so much.
She has a lot of early reader simple chapter books, thanks to the Book People, but again she's finding them frustratingly short on story (with the exception of the Tomlinson animals who are... ones, which she is loving). She really is ready for full on chapter books, but they need to be at her emotional level, because other than decoding and comprehension of basic plot, she's just a normal preschooler. Early Blyton's good there actually. She's loving those. And I'll buy the awful rainbow magic ones, after the fairy unicorns have been such a hit. Though I'm also having a rummage on the Mighty Girl site to find come countering feminist early readers! They have some good ones on Rosa Parks, Ruth Bader Ginsberg etc for smaller people. She loves the Paper Bag Princess so she may, hopefully, be receptive.
Sadly I can't go to the library, or take her, as it's too much of an infection risk for me when on chemo. I can't even eat live yoghurt right now and someone else has to do most of the playgroup runs as I could catch something which could make me extremely unwell, very fast. But I'll phone the specialist librarian, as suggested - that was so helpful, thank you for the person who mentioned that.
It's a bit weird for me as she reads so, so much better than her brother at this age, but has such reduced critical thinking and comprehension skills over him when he was a preschooler - he was running basic science experiments and watching The Wonders Of The Solar System and understanding actually quite a lot of it. We could read far more advanced things to him, but his reading at preschool age was the Songbirds level so there was no issue or question in terms of what he was reading to himself.
I suppose it's the old thing about assuming your eldest is what kids are all going to be like, and then the second being completely their own person. I should probably stop assuming that he's the very able one and not her, though, too, because she's learning different things at a different pace, and that doesn't mean either are any brighter or less so, especially as she's very tiny still.
I think many of you will understand when I say that having a very able, and also disabled, older child means I was and am hoping she's an excellent top end of average, because that's an easier and hopefully happier life for her than extremely gifted and ASD. People always assume parents with very able children must be showing off, or whining that there are too many diamond studs on their shoes, whereas we all know differently. He's currently home educated, because schools suitable for ASD can't cater for gifted in this county alongside. We're literally having to move house in the summer to be near one that can. So I am hoping her early reading is a lovely aberration in an otherwise high average child, frankly. I'm not writing her off by saying I think she's an averagely bright kid. I'm hoping that's the case. Gifted is a double edged sword in this educational system, unfortunately. Not one I want for her. I'm hoping you all understand that.
