Most preindustrial sources will emphasize that most lower-class people got their calories largely from grains because meat and other supplements were expensive, so you'd need a LOT more bread to feed a family than you would in modern times.
This article explains that a family/household of 10 people needed huge troughs to knead 7 US gallons' worth of bread per week. If a gallon of water weighs 8 pounds, you've got around 56 lbs of dough in the kneading trough, so one person needs five or six pounds of bread every week.
Nobody would want to knead eight or ten pounds of bread every day.
