Novels with kids, for adults
I've been reading some of Dickens' work lately, and I can't help but appreciate how he brings attention to kids. He was writing to adults mostly (well, to all ages), but all the novels of his that I have read have had kids as protagonists or as major characters (at least until they grow up). Were there others before him who really focused on kids, or was he starting something new there? I don't mean children's literature--I mean the concept of writing about kids so as to remind adults what it's like for kids, and to remind adults that kids have voices. Were there others before him (or during his time) who did that same sort of thing?
Also, did the fact that he wrote about kids change the way people perceived kids? I feel like it would, but I'm not sure.
It looks like even today, there are few authors who consistently write to general audiences but consistently write about kids at the same time. Flannery O'Connor and Harper Lee have done it, but they seem to be a small minority. Any thoughts?
