I sent passport application of my new born to Abu Dhabi Consulate today. It is fairy very easy process. Email them on the correct email address and they should share the step by step process. You must be sending emails to the wrong address. Relax and go to consulate website and book an appointment for Passport and Citizenship application there and they should return an email within 48 hours with instructions. if you have already applied for citizenship then you would only send passport application along with payment receipt and citizenship application confirmation to Abu Dhabi Consulate. Thats it and you are done.
I was able to get information from Canadian consulate and it is similar to what Samila explained above. I am providing additional details for anyone for reference in future but you MUST contact local consulate to confirm process as there are some caveats to this process to validate documentations provided by the country where child is born.
