I'm not being horrible, genuinely curious.
You read on here how a child who has autism or some other issue, will only eat safe foods. Usually a lot of things like chicken nuggets, a particular brand of cheese and onion crisps, Nutella, supermarket pizzas (UPF mostly)
Do we think children in the 1920s just went hungry? Or perhaps they were forced to eat foods they didn't like. After all you do hear stories,of adults even now being made to sit at the table and choke down food etc.
