How do we do an adoption without the need of an attorney?

It is going to be difficult. You can try to go to the Clerk of Court's Office in your county. Some Clerks are very helpful to unrepresented parties, while others simply tell you that they cannot give legal advice. Bottom line the Clerk of Court has jurisdiction over adoptions in North Carolina. Each county has its own Clerk of Court. Also, you are going to need the father's consent unless you first terminate his parental rights (which I would think is very close to impossible to accomplish without hiring an attorney, even if the facts support the termination).
