Ok, you need to know that unless you phone the LA you will not be on the waiting list for your nearest school. You need to contact them and ask to be added to the list. You should be quite high on that list, if you can see the school.
PoppyPia I feel for you, actually. You sound like you had an idea of how admissions would work logically, rather than knowing how they work actually.
It seems like your thought process went along the lines of:
-No point putting down in-sight CofE because we're not religious and if they don't give us our preferred schools he'll go there anyway.
-Put down 3 other schools which we might get a shot at.
Then, offers day comes and, shocked, you see that not only did you not get your preferred schools, you didn't get the local school.
So, you rejected the place offered, thinking that the LA would prioritise your DS because, after all, he doesn't have a place anywhere.
Now you're in a bit of a pickle.
