John Stamos can't stop sharing adorable photos of his son, Billy

The only thing better than a photo of the one and only John Stamos (and his incredible hair, obviously) is a pic of him with his baby boy, Billy.

The adorable son who the Fuller House actor shares with his wife, Caitlin McHugh, was born in April, and Stamos was instantly smitten. Fatherhood came later for him than for most — he was 54 — but he’s making up for lost time now, taking every opportunity to gush about his little one in public, snuggle with him, and, like a lot of dads, proudly display photos of his offspring.

He made hearts melt with his words about his first Father’s Day as a dad. Stamos also gave fans their first glimpse of Billy’s tiny face.

He paired some of Lin-Manuel Miranda’s “Hamilton” lyrics with a snapshot that was really more about father than son. Not that anyone minds…

Until Father’s Day, Stamos had been careful to obscure his son’s face in the images that he shared, but even then he showed fans enough to make us say, “Aww.”

This black-and-white snapshot of Stamos wearing a robe that reads “Daddy,” holding Billy in his arms, should be framed at his home. Come on, it has to be said: Have mercy!

Stamos makes everything look a little cooler. Truly, this should be a pro-voting ad.

Baby Billy already supports his dad’s Full House band, Jesse and the Rippers. Appropriately enough, he rocked a onesie with the band’s name on it when he met Stamos’s longtime co-stars Lori Loughlin and Bob Saget.

Stamos declared himself a changed man when he became a dad. Lucky for fans, he didn’t change too much.
