John Stamos is celebrating the 'little moments' with his son, Billy, in a trio of adorable photos shared to his Instagram.

John Stamos and his 4-year-old son Billy are having the best father-son moments together!

The Fuller House star shared three sweet photos of them together on his Instagram Thursday reflecting on the small but tender moments he shares with his little one.

In the first shot, John sat with his boy on his lap in a garden as the two of them laughed together, looking happier than ever.

He also included a sweet pic kissing his son on the head as Billy was wrapped up in a towel outside in the  backyard.

“The little moments. The ‘micro-transactions’ that take place in between life’s big events. I like those the best,” John captioned the post.

John loves sharing some behind-the-scenes takes with his family, recently also sharing a sweet post about his wife,  Caitlin McHugh, 35, to celebrate their 4th anniversary on Feb. 3.
