We had one car. I cooked a lot from scratch. Shopped sales. Used coupons. And we had really good benefits through the army, which we were both very savvy about because we both came from military families. Some folks join the military and have no idea how to take advantage of the bennies available to them. So look at whatever resources and benefits you may already have available to you that you might not be making the most of.
I also did daycare at home briefly.
You could pick up some books like "How to survive without a salary" by Charles Long and "The Tightwad Gazette" volumes 1-3.
