Tim and Siobhan Jackson from Co Down are celebrating the birth of their fourth child.
They welcomed Felix Laurence William Jackson into the world four days early, on Friday, February 15 at 11.55am.
The beautiful little boy weighed a healthy 8lbs 3oz when he was born at the Ulster Hospital in Dundonald.
"My waters broke at 4.30am in the morning, so there was a mad rush to the hospital," Siobhan said.
"Nothing was organised, as I was all set for a C-section on Tuesday.
"Tim and I are both relieved he was delivered safely. He's great. I think he looks like his brothers and his daddy."
Felix shares the same middle name as his paternal grandfather Laurence, and was given the second middle name William after his maternal great-grandfather.
He has been given a very warm welcome by his older siblings, Hugo (6), Amelia (5) and Monty (3).
Amelia was initially a bit disappointed not to have a new little sister to play with, but she soon came round when she got the chance to meet and cuddle her new baby brother.
Siobhan said the staff at the maternity unit of the Ulster were lovely and everyone is thrilled with the latest addition to the family.
"We've had lots of lovely messages coming through and lots of visitors," Siobhan added.
