I found a few good articles on wikiHow that relate to naturism and how to approach it in a family setting.
This first page is more of "
a tool for parents who want to teach their children a wholesome understanding of human nakedness."
http://www.wikihow.com/Practice-Nudity-in-Your-FamilyThis next page is how to "
slowly introduce your favored style of living with your family."
http://www.wikihow.com/Be-Naked-More-Often-While-Living-With-FamilyIf your confident and want to get your "
family involved in the nudist movement. Here's how!" If not, there are still some good tips worth a read in this next page
http://www.wikihow.com/Get-Your-Family-to-Be-NakedAnd lastly, an article containing tips for becoming a nude art model - things you should know, tips on being safe, etc.
http://www.wikihow.com/Be-a-Nude-Art-ModelThere are likely many more articles on wikiHow regarding naturism, and being a wiki site anybody can freely edit the content. If there are a few points that are incorrect or need to be elaborated on you may do so via the big blue "Edit" button above each section. This being said, the articles are subject to change by others and the content you read may be different from what I read on a previous date.
