I wish an official portrait to mark her birthday had been released. I know - the Wessexes value their privacy; they aren't THE family, and maybe Louise didn't want it, but - still!!
This is part of their appeal - they never make a fuss about themselves or about their children. The children come along but are not featured with photo series. You get to see them but they are not shoved into your face. They are not overly styled. They don't look for attention. They have internalized the principle of the firm "work hard, but don't fuss".
