Little Ava Hennessy is the first baby of the decade. As champagne corks popped and fireworks exploded to usher in 2010, Ava clocked in at just 28 seconds past midnight at Waterford Regional Hospital.
Her delighted parents, Rebecca and Shane, from Dunmore East, Co Waterford, were aware that the clock was ticking down on 2009 but just wanted her to lay eyes on her as soon as they could.
"The midwife said to me 'would you like her to be born in 2009 or 2010', and I said 'I don't mind', that was 11.20pm. I just wanted to see her as soon as possible," said Rebecca.
Ava tipped the scales at 9lb 5oz and is the fourth child for the Hennessys and she will have big brother Jamie (17) and sisters Abbie (11) and Danielle (6).
"Her dad is over the moon. The kids haven't seen her yet, we're just so caught up in the moment ourselves. The roads are so icy I don't know how my husband was able to make it back home to see them after the delivery," added Rebecca.
Just pipped at the post was little Harvey Hetherington-Kelly who was born at Mount Carmel Hospital in Dublin at one minute past midnight to parents Tanya and Stephen from Dun Laoghaire, Dublin.
"He's doing great, really well. He's a bit snoozy," said proud mum Tanya. "The girls were saying to hold off and not to push until five to 12," she joked.
Harvey, who weighed in at 6lb 7oz, is the second child for Tanya and Stephen who already have a two-year-old daughter, Amy.
"She's on her way in to the hospital now to meet him, she's very excited. We should get home on Sunday and I'm sure there will be a big party," she added.
The third baby born of the new year was was delivered at the National Maternity Hospital on Holles Street at 13 minutes past midnight.
Tegan O'Neill, who weighed in at 9lb 5oz, was born to overjoyed parents Carmel and Pat from Castleknock in Dublin.
"It was originally thought she would be born at around 10 o'clock but there was some hesitation on the baby's part -- she must have known," said her delighted dad.
"There was great excitement and it was amazing to see her coming. She's fit and healthy. It was a difficult delivery so we're just happy she has arrived whether it's before or after midnight," he added.
He described his wife as "amazing and a brilliant mum" and thanked the staff at Holles Street, including their midwife Mairead and consultant Dr Stephen Collins.
