Just put in the application asap and have a look around at other pre-schools in the area. I'm sure there will be somewhere suitable with a place for him.
Are you worried because you don't think he'll be able to go to school there once he is pre-school age? The school application process (assuming it is a state school) is separate from the pre-school process so you haven't missed the boat there. You cannot apply for a school place until the academic year before he turns 5. In our area the deadline for applications is some time in January (and I think this is typical for most areas) so you apply the January before the September when they are due to start. Most of them start at 4 (unless born right at the beginning of Sept in which case they may be 5 just before the start of their first term at school).
I am a new mum and all this is obviously new 2me. My son is 2 and 7mths basically will turn 3 the year 2014 in March and the catholic school i wanted him to go to "st james the Great" in thornton heath said its a bit too late though i can still apply and see what will happen='discretion Basis' i feel like my world is falling apart because had i known i would have started from day one. Any suggestions on how and what to do, because i really wanted him to go to this school? Thanx
