"It all seemed to happen so fast," he said, noting that Francis "came and touched all six of the kids' heads and gave them all a blessing, which was great."
The family left Rome Thursday night and returned to Germany, where Smith is stationed with the U.S. military. They didn't know about the Pope's Instagram post until the next day, when a friend sent them a link to the post on Facebook.
"It was a pretty neat photo, the photographer did a great job capturing it," he said. "It was pretty meaningful."

After living in Germany for two years, the family is set to return to the United States in six months, and had wanted to visit Rome one last time before going back.
"We basically just went to Rome to see the Pope," Smith said, explaining that they had initially planned to attend the general audience in January while visiting a friend in Italy, but had to cancel the Rome portion of the trip because the Pope was in South America.
However, it wasn't their first time meeting the Vicar of Christ. Though it was their first interaction with Pope Francis, Brian, Kelle and their three oldest children met Benedict XVI during his Mass for Pentecost in 2010.
"One thing about both of them is that popes love babies," he said, recalling that as soon as Benedict entered St. Peter's Basilica "he saw the children and he just ignored everybody else and came for the kids and blessed them."
"So my older three kids don't have an excuse," he joked, "because they've been blessed by two popes."
Smith said that while he is excited to return to his home in Texas for a few years, he has enjoyed living in Europe, where, despite a general decline in the practice of the Christian faith, "there's still so many great sites...Pretty much all of modern Europe is based on 1,000 years of the Church being here. So it's great."
Highlights of their time in Europe have included visits to Fatima, Orvieto and Lourdes, where Smith participated in the annual military pilgrimage to the shrine, as well as many other places where saints are buried.

However, Smith said perhaps the biggest highlight was having his son Bobby – who is named after Jesuit St. Robert Bellarmine – baptized by a Jesuit priest he knows during Mass celebrated at the saint's tomb in Rome.
"This has been a great posting for us," he said, "because you hear about things but America is not really a Catholic country, so it's great to be able to see all of these pilgrimage places, it's a great blessing."
