In the near month that it's been since Jack Stirrup welcomed his first child with girlfriend Kelly Hidge, the new Below Deck Mediterranean dad had yet to share a photo of his bouncing baby boy on social media.

Luckily, all of that changed on May 12 when Jack posted his first pic of son Phoenix Sidney Stirrup, who was born on April 15, on Instagram. The adorable photo shows the proud papa lovingly holding his son as he drinks from a bottle. Little Phoenix looks relaxed and content in his father's arms. Jack also looks the happiest we've ever seen him with a big grin across his face.

This momentous occasion caught the attention of several of Jack's crew members from Below Deck Med Season 4, who shared their well wishes for him and his family in the comments to the post on Instagram.

João Franco commented that Jack's son is "super cute" and joked that he "must take after the ma." He added, "Hope you're well brother."

Colin Macy-O'Toole shouted his congrats in the comments. "Yes brewww!!" he gushed. "Congrats bud!"

Anastasia Surmava called Phoenix a "sweet baby boy" in the comments, and Below Deck Med Season 1 stew Julia d'Albert-Pusey also liked Jack's post.

Jack's girlfriend, Kelly, has been sharing the most precious pics of Phoenix on her Instagram since the couple welcomed him into the world, including another gorgeous father-and-son photo. "My entire world," Kelly captioned the snap.
