Childcare after adoption

I have 3 lovely little child from foster care. They are 2,3, and 4. They are legally free for adoption and we would like to move forward. The problem is that I was just informed that after adoption we are responsible for daycare. In my area we are talking roughly $1000/mo each child. Who can affprd $3000/month. Surely there is something that can be done. DSS pays for full childcare now and they are qualified as special needs children, however SW’s say no childcare. I want them out of the system as soon as possible but I can’t afford that daycare. I mean I understand if it was just 1 but 3? If they were my bio children i wouldn’t dream of have having children back to back to back. I’ve heard that adoption agreeemnts are negotiable. Is this something that can be negotiated? I’m in NC by the way.
