Medicaid?

So I've been reading up on getting Medicaid for my baby after he's born just until I can finish school next year. Everything I've been reading has said that I'll have to go after his father for child support before I can get any kind of government assistance. I REALLY don't want to have to do this because he's an asshole who I don't want to deal with anymore and I'm afraid if his parents find out they'd try to take my baby away. Does anyone have any information regarding government assistance and child support?
