The infant, who weighed 6lb 11 oz, arrived into the world at two minutes past midnight at St Luke’s Hospital in Kilkenny.
She is the third child of Breda and Leo Hogan, Lowhill, Ballinakill, Co Laois, who already have two sons - Cillian, four, and James, three.
The first boy for 2006 was born in Limerick at three minutes past midnight.
Calvin Nash, who made an early arrival, was born at Limerick Regional Maternity hospital and weighed 6 lb 5 oz.
His proud mum, Edwina, said she was “over the moon” yesterday despite feeling exhausted after her 40-hour labour.
“My due date was not until January 8 but I went into labour on Friday at 7am,” she said.
A native of Askeaton in Co Limerick, Edwina was accompanied through her long labour by her mum, Rose.
“He is the first grandchild too so everybody is delighted,” said Edwina.
And at four minutes past midnight in the Rotunda Hospital, Dublin, Louise Leonard from Coolock, Dublin, gave birth to a little girl who weighted 9lbs 11 oz.
The infant made a late arrival - her birth was originally expected before Christmas.
While Louise has not named her child, she has narrowed her choice to just two, Clara or Molly.
It is Louise’s second child. Her older daughter, Meggan, three, had wanted to call the new baby Charlie but will have to think again.
Tessa Hannifin, originally from South Africa but now living in Wilton, Cork, was not surprised that her little daughter arrived at 2.03am on New Year’s Day, her due date.
After a short labour at the Bon Secours Hospital in Cork, the little girl arrived weighing 7lbs on the dot.
Tessa and her Cork-born husband, Bill Hannifin, who already have a two-year-old daughter, Sarah, have yet to name their new bundle of joy.
Tessa was delighted with the care she received at the hospital - one of three maternity hospitals in Cork to be amalgamated into a special maternity unit at Cork University Hospital later this year.
History repeated itself for Joanna Dedman, who now shares her New Year’s Day birthday with her son, Oliver Childs, who weighed 7lb 12.5 oz.
He was born at 8.58am in Tralee General Hospital in Co Kerry yesterday and was the third child born in the hospital after midnight.
Joanna, from Garrynadur, Lispole, Tralee, who was born on New Year’s Day in 1974 said both she and her son also arrived into the world two weeks earlier than expected.
Joanna and her partner, Charlie Childs, already have a son, Thomas, two. The couple, originally from England, arrived in Ireland eight years ago intending to stay just three months but fell in love with the country and now have a restaurant.
