Thanks for the replies.
I know that several countries do apply the six month validity but what I was trying to say was that it did not seem to be widely advertised on this website otherwise I would have been aware of it and been able to apply for my son's passport in the usual fashion and save both time and money, not to mention stress (no blame to the website, its very informative - just a comment). It may well be a topic that has been brought up and I've just not researched it as it never occurred to me that Turkey was in the 6 month category.
As I said, never mind - a lesson learned, will get up to Glasgow on Monday and get it within the week.
Cheers
