I got my children passports last week, after 49 weeks of waiting. I was advised that my children were not eligible for an ETD, as the concession that the home office put in place last year to ease the backlog, was withdrawn around October last year. Try your local MP. Mine was very good, although they could not speed up the process, they have a hotline to the passport office and can find out about your application straight away, but they will not give you a timeline.
