If your girlfriend lived with you for the entire tax year and had less than $4700 of income, then you might be able to claim her as a "qualified relative" and get the $500 credit for other dependents. You CANNOT claim her child as your qualified child, since you are not married. If the child lived with you for the entire year, you might be able to claim the child for the $500 credit for other dependents. You do not get the child tax credit, earned income credit or Head of Household filing status for claiming your GF's child.
Not sure what you mean when you say your GF "does not make enough to file. " How much did she earn? If your GF worked and earned some income, it would likely be better for her to file a tax return and claim her own child. She might be able to get earned income credit and the child tax credit for claiming her child. If she claims her child, then you cannot claim either one of them as dependents on your tax return.
