Exactly Charlyn they kept congratulating themselves on all the food they had produced, which was great but surely there is a limit to what they could either use fresh or store for future.
Selling their surplus, eggs, fruit, veg etc could provide a small but steady income to say, offset the cost of a small freezer once they have the house finished or put aside for the kids shoes/ clothes in future as they grow.
I couldn't live that hand to mouth with such small kids to care for. One period of illness/ minor accident to either parent that meant they couldn't work would be catastrophic.
