What Would The Poor Childrens Food Been In Victorian Times?

Gin, mash, porridge, and laudanum would have featured heavily in the menu.  Gin, the infamous alcohol, was a technological development that allowed people to drink the water- remember, they just drank from streams and wells in those times, no filtration and boiling before drinking, although it was known about, wasn't common.  The invention of gin, a cheap, colorless, tasteless alcohol by a dutch chemist, meant that the working class got sick less often, as the alcohol was an anti-bacterial agent.

potatoes and grains were relatively cheap. Milled flour was plentiful, and white flour, from a new milling process, was first known about in victorian times and heavily marketed as being better by virtue of 'white being the color of nobility'.

last but not least, laudanum- an opiate- was widely used by the working class. They used it in nurseries to keep the babies from crying. Working class people used it on a daily or weekly basis for any conceivable ill, from sneezing to headaches to cramping and tumors, that they could think of as an excuse to use it.it was even (somewhat successfully) used as birth control by prostitutes of that time, as opiates disrupt the ovulation cycle.
