I'm not sure what you mean by signing the birth certificate. I can say that the best way to resolve the situation would be for you to adopt the child. After the adoption, they will issue a new birth certificate with your name on it. This requires a court proceeding, but it may not be difficult if the birth-father either consents to the adoption, or at least does not oppose it.
