Dad-To-Be John Stamos Honors His Late Father With Heartfelt Throwback Photo

Then, Caitlin came along and changed everything. 

John proposed to the 31-year-old at Disneyland in October, but revealed to People that she’d already told him she was expecting.  

“The [pregnancy] happened. Then I said, I better have a ring on her finger because it’s the right thing to do, and I wanted to marry her anyway,” he told the mag.

John’s “Fuller House” family already knew he had a special fatherly instinct. Last month, Jodie Sweetin told Access that John is known jokingly as “the baby whisperer” on set.

“John has wanted kids for a really long time. He’s so great with kids,” she said.
