Bethany Hamilton's son Tobias is taking up the family business! Last week, the surfer shared a few sweet Instagram snaps while teaching her 2-year-old how to surf [1]. "My favorite kind of party wave," she captioned one of the photos, which showed little Tobias standing up on a board and catching a wave. Also in the photo was Bethany's husband, Adam Dirks — a Christian youth minister and fellow ocean-lover — as well as Bethany's growing baby bump. In early October, Bethany revealed that she and Adam are expecting their second child [2]. The couple tied the knot in Hawaii in August 2013, 10 years after Bethany lost her left arm in a shark attack [3].
