Christopher Furlong/Getty Images(CNN) - Only four sets of triplets were born in Northern Ireland between 2017 and 2018, according to the province's Public Health Agency -- and yet in one hospital last week, two healthy sets were born within 24 hours.
Claire Stewart told PA that one thought sprang to mind when she learned she was carrying triplets: "I'm so glad my mum is retired."
According to father Johnny Stewart, there were more than 20 members of staff in the room during Claire's labor, but the birth was "very calm" all the same.
Zoey, Cameron and Brody McMenamin weighed between 4.7 and 5 pounds, while Annie, Libby and Evie Stewart weighed between 4.4 and 5.1 pounds, the South Eastern Health & Social Care Trust, which includes the Ulster Hospital, said on Facebook.
"We haven't really got used to the idea there is five of us yet," Johnny Stewart told PA, explaining that the triplets have remained in the hospital as two received special care.
