I'd taught dd1 her phonic sounds, and she was putting them together to read, writing her name, and numbers, that kind of thing. However, despite a lot of trying, she still wasn't dry at night, able to put her own shoes and socks on, able to use a knife and fork well, doing her coat up etc.. If she had been more agile and better at doing the latter things, it would have made Reception much easier; they are much more important than being able to read already! She's now Y2 and although doing well academically in general, her young age is still an issue, partly with spellings, which she is slower to learn than average, and partly getting changed, eating her lunch nicely, etc..
ds went to the schools own nursery where they start teaching them phonic sounds (in a very fun way), to write their name, etc.. He showed no interest, wouldn't sit down for such activities, and didn't absorb any of it! He was better at dressing himself, table manners, etc, than dd at the same stage though. So far Reception is going really well! His teachers insist that he is learning everything he should be learning at the right time, even though writing (even his name) is still slow and laborious. He has learnt all his phonics the first time they're presented to the class, and began reading (blending phonic sounds together - this is what schools want) just before christmas. He is coping with full days just fine; actually isn't as tired as dd after school, which is just the difference in their stamina and temperament.
Helping your dd to be able to do all the ancillary things (shoes etc..) will be much more support to her than the academic stuff - all that is what you're paying the school for! So don't worry a all, sounds like she'll do great!
