Sometimes it's fun to do a "kids only!" mini session, usually for the purpose of Christmas cards. But just be warned: I will convince the accompanying parent to be in at LEAST one photo. Because in ten/twenty/however many years, your kids will be grateful. Not that you won't be around. Just because they'll want to see you when you were young. Not that you won't be attractive when you're old. Nevermind... this is getting awkward.
Wiens family, enjoy your preview! :)
