Laura and Gary McKeown from Lisburn are celebrating the birth of their third son.
When Isaac John McKeown was born at the Royal Victoria Hospital in Belfast on October 8 at 10.08am, he weighed 8lb 2oz.
The handsome baby boy's middle name is John, after Laura's grandfather, John McAdam, who sadly died in June of this year.
Laura (29) and Gary (30), both civil servants, were relieved when Isaac was born healthy, as they had lost a daughter, Katie, just hours after her birth in 2010.
Laura praised the care at the Royal following Isaac's birth by Caesarean section.
"The staff were brilliant," she said. "I had to have a small operation after the Caesarean, as I was getting the worst headaches, and they were absolutely brilliant checking on me and helping with Isaac."
Little Isaac's elder brothers, Callum (7) and Ethan (2), are enjoying the new addition to the family.
"They both love him," Laura added. "Callum is brilliant with babies and can't wait to get home from school to see him.
"Ethan was wondering who this baby was that I was holding, but he is starting to come round now."
And Laura says her husband is a very "hands-on dad".
"Gary is great," she said. "As parents, we have more of a clue now than before.
"I'm much more relaxed this time and everything is going well.
"Our friends and family have been great, especially my mother-in-law, Valerie."
