New parents Beth and Matt Sullivan were "over the moon" to welcome their first child, but admitted they were not expecting her so soon.
"She was due on January 22, but she decided to come a wee bit early," Ms Sullivan said.
"We were very very surprised when I woke up in the middle of the night having contraction pain."
Abigail was born in the Queen Mary Maternity Centre at 11.40am, weighing 3.37kg (7lb 6oz), and was delivered by midwife Alana Dunn.
"It is crazy — we did not think this would happen," Ms Sullivan said.
New Year’s Day was a good day to celebrate, particularly as the couple, both nurses, had worked throughout the challenging times of the Covid-19 pandemic.
It was good to begin 2021 in such a positive way, she said.
"It is something very exciting to start the year with.
"We are both very happy — both very tired."
