Custody vs. Adoption

Oh, forgot to mention, Xena will get Medicaid until 18. Not sure if its because if her medical issues though. And they can still file for child support regardless of whether or not they can pay it I believe. What does child support have to do with adoption? I've heard after a year I can file o adopt but I honestly don't much about it...paperwork says parents need to consent if we do file for adoption. The only financial support we were offered for guardianship was Ohio works first. They have a child only grant that is not based on income but you have to be willing to go after parents for child support. We decided not to mess with it so I'm curious about how that would affect if we can adopt down the road.
