James Van Der Beek revealed his biggest parenting regret amid his cancer battle as she shared a new reflective social media post. The actor celebrated his son Jeremiah in a tribute post uploaded via Instagram on Friday, October 10 to mark the child's 4th birthday, while apologizing for not being a better father amid his health struggles. "4 years old today. After 2 late-term losses, we thought we were done. Thank God you knew better," James, 48, wrote alongside a carousel of photos of Jeremiah, including one where the child was perched atop the actor's shoulders.
