Sahm returning to work. How to afford daycare for baby?

I don’t have a college degree or anything because I was a sahm since the age of 20 and my ex husband made a decent living. I’m newly remarried (1.5 years) and he doesn’t make as much as my ex, but we do okay. I plan to return to work shortly after my baby is born but I’m afraid I’ll be working solely to pay for daycare, which is counterproductive. Any advice? Is there free or cheap day care for babies? In Atlanta area.
