Hello,
Congratulations on the birth of your child, and sorry that you gave birth to her through cs.
To your enquiry, firstly why are you illegal in Germany especially when you are expecting a baby?
Even with a Duldung, the State would have cover the expenses, as it is now, you need to **** out for NGOs that can bail you out like CARITAS, DIAKONISCHES, or FRAUEN organization for women.
Am sure there will be a way out for you.
Goodluck.
