Samuel Hanak arrived in the world just over an hour-and-a-half after his parents stepped through the doors of the Ulster Hospital in Dundonald.
Full-time mum Dana (33) and Jan (36), a hotel manager, are thrilled to welcome another healthy boy to the family.
“It was a great feeling,” Dana said. “He's brilliant. He changes every day.
“He has the same nose and mouth as his daddy.”
Samuel weighed 8lbs 4oz when he was born on Sunday, October 20 at 1.53am.
“It was very quick,” Dana added. “We arrived at hospital at around 12.20am and Samuel was born at 1.53am.
“The staff were brilliant, really friendly. They really helped us, all the midwives and doctors were great.”
Big brother Honzik (2) is “a little bit jealous” of the new arrival.
“He told him to wake up and is asking him questions, but he doesn't want to play yet.
“He's a little bit jealous, but he's getting used to him.”
Dana explained her husband is a very hands-on dad and has been helping her a lot with household chores.
And she's looking forward to her mother coming over from Prague to stay for a few weeks to get to know her new grandson.
“I want to thank the Ulster Hospital staff and my husband for all his support,” Dana added.
