Just had a look at the Dominos post and someone asked how much it cost, so of course lots of big families chimed in to say that bigger families are better at budgeting so spend less on food than small families
One said she has 9 children and a budget of £50 per week and eats really healthily. An example was a meal of a bag of pasta, a tin of chopped tomatoes 2 tins of tuna and a handful of frozen sweetcorn for only £1.50. How the hell she's feeding 10+ people on that beats me. There must be a rule that the more you have the smaller the portions get. Intentionally feeding your children less food because you want another child is absolutely grim.
