I would not worry. When doing this kind of reporting myself, I never received back the confirmation before lapse of 6-8 weeks. 

Look into “Recognition of paternity” through your local embassy. It was a fairly straightforward process not involving the government departments of the child’s nationality, hence making it easier, as long as you can fulfil all requirements of your local government.
An additional “plus” was be that the child got immediate citizenship of your country with all the rights and obligations on your and the child site as if it would have been your biological child, of course depending on the regulations of your government. Did that myself with a child of Philippine decent with the German Embassy in Thailand.
