Kristin's oldest child, Camden — or "Cam" — was born on Aug. 8, 2012. On his sixth birthday, Kristin posted a rare photo of his face in a baby photo, sharing that he'd started calling her "Mom" instead of "Mommy." Then, on his seventh birthday, Kristin shared the above photo on Instagram with the caption: "Happy birthday to the man that I love spending hours talking to. The oldest, deepest soul I know, my little Cam. Love you, buddy." Aw!
