Welcome to the Wefugees Community and thank you for your question.
We discussed the issue of how to obtain birth certificates for newborn children at the Standesamt a couple of times before on this platform. You may want to read the information given in this thread, for instance. Please check this document as well. It gives a good overview on the procedure.
In any case, please don't hesitate to get back to us with any further questions.
All the best,
