DD is 4, she will be 5 in February. She has been in FT school since April, but we are in Wales and they don't really push reading in Reception.
She isn't a PFB, she is my NTB (Neglected Third Born).
We realised that she could read during the summer holidays, I think he older brothers have been "teaching" her. She can now read simple books, roughly around ORT Level 2 I would say.
She knew all of her letters before she started school. She can spell fairly simple words quite accurately (things like cat, dog etc) and has a go at longer words. Her teacher says that she is doing "very well" and she is put in a little group of older ones to do reading etc as they are ahead of some of the class.
DS2 (who is now 6) could read in Reception too, probably at roughly the same level at the same age, but didn't write as well as she does so I don't know if he could spell as well as her.
DS1 (who is now 8) couldn'r read at all in Reception, he didn't start reading or writing properly until he was in Year 1 aged almost 6.
DS1 and DS2 are both at the top end of their classes now, especially for reading. So it all evens out in the end, late starters catch up and often pass those who started early.
I certainly wouldn't worry about your DD, she sounds just fine to me! There is often a lot of pressure to read early, but there is no point pushing it if the child isn't ready IMO.
