The Nashville star posted the lovely capture of himself lying in bed with his daughter, adoringly looking at her while she munched on a pack of chips.
"The old pics that pop up on my phone are killers.. a solid mix of joy and pure devastation…," he admitted in his caption, and his family were just as much in awe of how time had passed.
Goldie left a like on the photo and a comment reading: "Precious moments," with a heart emoji, as did his sister Kate, a mom-of-three herself.
A fan commented: "Those kinds of photos are the reason we had baby #3! Couldn't bear that it was over," with another saying: "I hear you. Beautifully said."

A third also reminisced: "I’m right there with you! It goes way too fast," with a fourth writing: "'Solid mix of joy and pure devastation.' Perfectly said. And pure love."
Oliver's children with wife Erinn Bartlett are all grown up, with the latter recently taking to Instagram to share a glimpse from their latest family vacation.
The Hudson-Bartlett bunch went on vacation with the actress' side of the family, and had a "magical" time enjoying Cape Cod's sunny beaches.
Plus, with each picture that showed the three children smiling ear to ear and proved how fast they are growing up, naturally fans were divided on who they are growing up to look like more.
