Family photos are priceless. I strongly encourage families to do a portrait at least every 2 years. The time you have with everyone together is so valuable, and young people are constantly changing. Capture these moments you have together. You'll never regret it! Someday these images will serve as a record of your family's history, and they're worth every penny.
That means you too, MOM! Nobody cares if you have a few pounds to lose or your hair isn't perfect. Your children love you just like you are - flaws and all!
And don't forget... family photos don't always have to be formal. What kid doesn't love dressing up like Superman every now and then?
