How often should you take family photos?
This is a two part answer,
First part of this answer is: I have found that families who have family photos taken more often, are not only much more successful at having a beautiful and meaningful session, but they also enjoy them more.
Ideally every year you would update your family photos with a professional photographer. As well as document mile stones and key life events and celebrations like :
*Birthday
*Wedding / Engagement
*Anniversary
*New Baby / Maternity
*Graduation
*Extended family gathering / Family Reunion
The second part of this answer is:
Always be documenting your life, hire a professional photographer, take selfies on your cellphone, record your spouse and your kiddos doing silly things, have a friend with a camera take a few snaps.
So the answer that comes from my heart is every chance you get, because time is not a renewable thing, you can’t redo or get time back. Speaking as a mom myself, every moment is precious.
