The Doocy family is reveling in how special their Father’s Day is this year.

This year marks the first time Fox News White House Correspondent Peter Doocy, 35, will celebrate the special occasion as a dad, having welcomed daughter Bridget Blake in February with his wife, Fox Business reporter Hillary Vaughn.

It also makes for the first year his dad, FOX & Friends host Steve Doocy, 66, will be celebrating as a grandfather — to both Bridget and daughter Sally’s baby boy, Arthur, born just three weeks after Bridget.

“Watching my parents’ faces the moment they laid eyes on my daughter Bridget for the first time, just a few days after she was born in February, was one of the most special moments of my entire life. It is something I think about a lot, and it is something I will never forget,” Peter tells PEOPLE.

“In less than a month, we had a grandson and granddaughter—both healthy and happy…talk about lucky,” Steve tells PEOPLE of his and wife Kathy’s joy at becoming grandparents.

Though they celebrated early with a father-son pickleball game and will enjoy some moments together over FaceTime Sunday, it’s the big picture of what this new chapter means for the Doocys that excites everyone.

 “A few years ago Kathy and I wrote a book on fatherhood, we used this quote; ‘There are three stages of a man’s life: he believes in Santa Claus, he doesn’t believe in Santa Claus, he is Santa Claus.’ Now with grandkids, we intend to be Mr. and Mrs. Santa Claus every day—and can’t wait for Christmas,” Steve says, joking, “Kathy says she’ll need a forklift at the toystore.”

One of the big takeaways from his dad’s parenting that Peter is eager to continue is making sure every moment is documented.

“My parents and my wife Hillary’s parents both live out of town. Luckily, I learned from my mom and dad as a kid how important it is to get as many photos and videos as possible – clips we will have forever – but can also share in real-time – making sure that in between visits, everyone is getting baby updates at the speed of a group text,” Peter explains. “And we can’t wait for Bridget to get a little older, so she can update them herself, via FaceTime!”

“Having majored in journalism, I made sure our three kids were 35 mm photographed and camcordered at every significant event in their lives,” Steve laughs. “Now with 35 years of family photos organized in a giant online album, when Peter sends me a photo of his daughter, I’ll find a corresponding historical photo of a Doocy baby at that exact age, and split screen them.”

The grandparents — who say they’ll let their grandchildren decide what they’ll call them — also plan to continue recreating shots of Peter as a baby with him as an adult, and now, with his own baby in tow.
