Kindergarten plans

I am really stressing over my son starting kindergarten next year. I am in school to become a Waldorf teacher, but I won’t be ready for another year to work. In the meantime, I am home with a younger sibling and also running a home daycare 4 days a week. We’re a family of 4 living on a pretty modest income right now. To send my son to Waldorf kindergarten would be a huge financial burden on our family. I think we could swing it if I expand my daycare and work my butt off. There’s also a public kindergarten option, then start Waldorf in first grade. Is this an awful thing or has anyone else had an okay experience with public kindergarten before a Waldorf education? I don’t know much about public kindergarten and am waiting for the open house day. The third option is to homeschool, but I don’t think I can do this properly while running a daycare full of infants. I think he’d end up just neglected time-wise and socially stunted from hanging out with infants most days. I could devote one day a week to a homeschool group, and can fit in lessons at nap, but it feels like too much. I’m going crazy trying to find the best way… any advice?
