Heidi cradles her baby boy while surrounded by beautiful white flowers in the new photo.
She and Spencer posed together with Gunner a few days before. What a sweet family portrait!
The new parents are clearly loving playing mom and dad.
The couple also took their little bundle of joy to a pumpkin patch for the first time! "Best fall of my life!" Heidi wrote on Instagram.
Gunner was also super adorable when he went as a burrito for Halloween, and Spencer and Heidi were Taco Bell employees.
