Dear
@Guly,
It is not wrong to send the documents to the Federal Office in Nuremberg. This office will forward the documents to the office responsible for your child, which will then contact you and your partner.
Unfortunately, the birth of your child has no influence on the outcome of the asylum proceedings of you and your son. Only if your newborn daughter is granted refugee status or subsidiary protection in her asylum procedure, this could have a positive effect on the residence situation of you and your son.
Best regards
