Laura and Andrew Foote from Lisburn are celebrating the birth of their son Reuben.
Reuben Andrew Foote was born at Lagan Valley Hospital's midwife-led unit on August 6 at 5.31am.
The healthy baby boy was weighed 8lbs 6oz and measured 51cms.
Laura explained they waited to find out if they were expecting a boy or girl.
"He was a surprise," she said.
"We were so happy to see him. We are ecstatic it was a wee boy. He looks like my daddy.
"He was a bit of rascal at the start. He's a hungry baby, a good wee thing."
Big sister Arabella (2) is adjusting to the new addition to the family.
"It's taking a few days to settle her with him but she's getting there," Laura said.
The proud mum praised staff at Lagan Valley.
"They were absolutely fantastic," she said.
"I couldn't rate them highly enough. They provided top class care, they had all the time in the world for you."
The Foote family are enjoying watching Reuben thrive.
"We are looking forward to getting out and about together as a family of four," Laura added.
Family and friends have been of great support since Reuben made his arrival in the world.
"We have a great set of family, they are up all the time helping look after the other wee one," Laura added.
