"If it's possible to bring you and your wife closer together, something like this really does," Romo, 32, told PEOPLE during a recent photo shoot for Starter athletic wear.
"It strengthens your family values and your family and the love you have, which is already really strong. It's been a great blessing from God to put us in this situation. We feel very honored."
The Dallas Cowboys quarterback says it's "definitely hard" to be away from his baby and beautiful wife, 25, but knowing she is supportive of his career makes being away for work that much easier.
"If you get a great wife who understands the demands of someone in athletics, I think that's important," Romo explains. "I was lucky enough to find someone like that. She's a great mom and a great wife. It's been fun just hanging out with her and my son. It's been exciting."
Romo and his love have already even witnessed a little milestone.
"You want to see everything," he says. "At 3 weeks old, we were having him lay down, and we put him on the floor. And all of a sudden he just rolled himself right over. That was pretty neat to see."
Being a good father shouldn't be too challenging for Romo, who has already enjoyed acting as a role model in the athletic community.
"It's a wonderful position to be in, to have the ability to affect some of America's youth when they see you and you're working hard and doing things the right way," he says. "Little do you know that some of the choices that you make are being watched."
"It's a brand that represents high-quality performance gear at an affordable price," he says. "Growing up, that was something I always looked for because I was going through shirts like they were water."
