A host of former Kangaroos returned to the club with their youngsters on Thursday for North Melbourne's annual Father-Son Day.

Amid the senior team's training session at Xavier College and the heart-warming announcement of Cooper Harvey's debut, 13 potential future Roos hit the track before heading over to Arden Street for a look around the club.

Lenny, Ryder and Noah, the respective sons of Michael Firrito, Lachlan Hansen and Scott McMahon, all experienced their first days in the program.

"Lenny was pretty rapt and excited, he was up last night asking, 'when can we go?' … and my younger one Max, he's chomping at the bit to get involved too so it’s a great initiative by the club," 275-gamer Michael Firrito told NMFC Media.

Not only does the program offer an opportunity for the sons but it gives the past players a chance to meet up with long-time friends and former teammates.

"Everyone is busy with life, work, family and everything so I don't get to see the older boys as much anymore, but it was great to see Sav Rocca, Shannon Grant, Troy Makepeace, Dan Harris and the other guys," Firrito said.

"It was good to catch up with some of the young boys because there's a few here that I used to play with.

"We're big supporters these days so we know all of the players but there are some I haven’t met before so that was exciting, too."

For Hansen, it's been a long time between visits, but he was delighted to back at North Melbourne alongside his son, Ryder.

"It’s the first time I've been back for about six years," he told NMFC Media.

"I've gone to games a few times and taken the kids but to be back and see a few players I used to play with has been terrific.

"He (Ryder) loves his footy, and once he found out when this was on he couldn’t stop talking about it."
