Along with passing on the family name, for some people who have children they also want to pass on their love for their county.
Speaking exclusively to Off The Ball on Tuesday, David Brady joked with host Joe Molloy about the lengths he went to to ensure his children grow up a Mayo fans.
“I used to play the Green and Red of Mayo to my wife’s stomach. Now, this is the night before an All-Ireland final - 2014 or 2016,” Brady joked.
“[My daughter] knows it back to front but she’s gone as smart now, she sings the Blue and Navy of Dublin.
“And I’m going, ‘you little…,’” Brady laughed.
“She loves the way it rises me, but you know what?
"It’s about football, it’s about GAA, it’s about young people,” he explained.
For Brady, beyond all the joking about trying to make Mayo supporters out of his children he just wants them to have an appreciation for sport and the fun that it can bring, he said.
Although he’s fighting against the popularity of the Boys in Blue while raising his family in the capital, his efforts may be paying off.
“She was at the National League final last year - her first day - and she still talks about the hotdogs, the fireworks and the green and red of Mayo.
“That’s when it all came to her and next week she was down in Castleknock GAA saying, ‘I’m going to GAA, Daddy.’
“She was expecting cups and streamers and the whole lot, but it’s what it all represents and the positivity it has for young people,” he said.
Whatever the outcome though, he’s happy that young people in Dublin get to see a great time at their peak.
“I think it’s absolutely fantastic that every child in Dublin is getting to see this glory era and Alan Brogan said he’s going to be buying my young fella his first Dublin jersey,” David Brady laughed.
