I had a household with twins who were still child aged and the parents were dying. I didn't want to lose the children to "the system" so I moved them in with the Pancakes as 'groundskeepers' then realized children can't garden (Eliza in that save had extensive gardens) so they stayed in school til they were old enough and ran the household as teens and young adults. I didn't let either one drop out of school to do their duties, but it kept them in my game rather than shipping them off to the limbo the game puts them in when they go into protective custody.
