Welcome back to the Wefugees Community and thank you for reaching out to us.
If your child is born in Germany, you need to apply for the birth certificate in the responsible registry office (Standesamt). In the linked information sheet you may find a list of potentially required documents for the process.
However, every state official in the registry office works more or less independent, which can lead to a varying in terms of requested/accepted documents (incl. translations). I would recommend you to consult the local "Standesamt" and ask them directly.
I hope this helps and please get back to us with any further questions.
All the best,
