I don't remember at all being short of food when I was a child but, from what Mum told me (she's 82 now), we were in the 50s, and she often went without. As a result, she has quite brittle bones and, sadly, her skin reacts badly to calcium tablets. I suspect many more mothers were ina similar situation
As for kids getting everything they ask for, our two daughters (now in their 30s) were never brand conscious, which some were then, and many more seem to be nowadays. Our younger daughter despairs of little girls being dressed up as little adults, and being given everything they ask for, except attention from, and play with, their parents. She was working at a wedding reception in an hotel, where there was one mother getting very drunk via a hip flask in her handbag, while her two young children were playing on the stairs, getting in the way of staff. The younger one, just 4 years old, eventually fell and broke her arm, and her mother tried to sue the hotel! Very sad.
