Since the child lives in Florida, you would go by the Florida guidelines. I have put a link to a Child Support guidelines web based calculator below. It sounds like there isn't an order in place - be very careful to keep receipts of the money you send to her as she could file for Child Support and you could be ordered to pay arrears - any proof you have that you have been supporting the child will be helpful.

Even if you are unemployed, the courts here would impute minimum wage income to you. Is there a current child support order? If the child is in Florida, then the Florida guidelines would be used. The child support amount would approximately $282 plus a portion of the health insurance and childcare expenses for the child.
I agree with my colleagues that Florida would be the home state of the child and enforcement of any child support guidelines, arrears, etc. I also agree that you should keep strict receipts of all monies paid to the mother. If she ends up filing any type of child support action against you please make sure to contact an attorney right away.
