My daughter is enamored of all things old-fashioned and loves shows like "Little House on the Prairie" (the books, too) and we've been watching the BBC series "Victorian Farm" and "Edwardian Farm" and she likes those, but wants something with kids in it.
She's 5 1/2, so dramas with adult themes and violence probably aren't a good idea (otherwise I would have her watching Game of Thrones - sure it's not technically history, but it is old-fashioned and there are children!). She's reasonably mature and has no issues with farm animals being slaughtered or realistic stuff like that.
Any ideas? It doesn't have to be documentary or even based in reality - fantasy movies or tv series would be ok as long as they're not excessively violent.
