Sorry, OP, have read my post again and think I was having a bad moment. I wouldn't normally pick up for grammar.
I was only asking who the 'they' were because I didn't know who you meant.
In the rest of the post was trying to be lighthearted because I think that everything to do with children, from the minute you find you are pregnant, is designed to make you doubt yourself. Clearly I failed and so if you took what I said as a dig, I'm sorry.
I personally didn't read any books, so have no idea what they might have said. Once you are in the system you will also understand it. It is as clear as mud tbh, and I had to think before I put the ages down. Other parents will only understand more if they have older children or inside knowledge, other than that they will be repeating hearsay. What I'm trying to say is that there isn't a secret club that everyone else is part of that has passed you by.
A lot of the stuff around primary framework/National Curriculum/EYFS is only really understood by teachers because we're the only ones who use it. We generally only know and understand the specific areas we are working in too, because it is complicated - and big. Oh and changes on a whim of the current government - the online primary frameworks and QCA schemes of work are currently archived.
And understanding a lot of the acronyms etc is just jargon that you will either come to understand or realise isn't important for you.
The school admission system had changed by the time my DD started school, so my prior knowledge was useless! I think I'm just a bit jaded because I see so many parents trying to prepare and being made to feel that they're just not doing enough - when generally they are and things change so much anyway.
The EYFS is freely available to anyone online, for example here which covers development from birth to 5.
Sorry again, if I came across as a bit of a bitch - I'm not!
