John Stamos’ house has become a bit fuller.

Congratulations are in order for the Full House actor as he has welcomed his first child with  wife Caitlyn McHugh. The couple announced the birth of their baby boy Sunday through Instagram. The couple announced their pregnancy late last year and got married in February.

Barely a day old, the little bundle of joy already has a name which John revealed on Instagram, complete with an adorable black and white photograph.

The 54-year-old unveiled his son’s name – Billy – after his own father.

“From now on, the best part of me will always be my wife and my son,” the actor captioned the sweet snap of his son resting of his chest.

Congrats, you two!
