Sadhbh Devlin and her husband Mark, from Bray, Co Wicklow, held a naming day for their twin daughters, Lile and Sabha, when they were a few months old, in July 2010.
"We're not religious but we really wanted to introduce the girls to our family, friends and village community and celebrate how important their arrival had been to us," explains Sadhbh.
"A lot of our guests had never been to a naming day so had no idea what to expect and some of the family weren't too happy that we weren't christening the girls. But they ended up being quite moved – it was clear how much the day meant to us."
The couple held an outdoor ceremony under a floral arch, where guests later attached personal messages to the children. A close friend acted as celebrant, the parents spoke their girls' names, explained why they were chosen and made promises to them.
"We promised to teach them honesty, generosity of spirit and tolerance and that we would do our best to teach them about responsibility, not only to each other, but to the world in which we live," says Sadhbh who writes a parenting blog, Where Wishes Come From (wherewishescomefrom.blogspot.ie).
Their 70 guests then moved indoors for a reception at The Grove Bar, Delgany, Co Wicklow, with the event costing the couple around €700.
"It was a magical day, and much more than just 'a christening without the church', it was completely different and special to us," says Sadhbh.
