Homesteading simply means producing some of your own foods. Whether you have a window sill, backyard, or acreage, you can improve you physical and mental health by growing, preserving, and creating healthier options, even on a budget.
We raise milking sheep and previously had milking goats. I always had problems with milk as a child and now, even with autoimmune issues, I can consume the dairy produced on the homestead most of the time.
