Victoria Lasita, 39, has given birth to her second set of triplets. The babies were born after 34 weeks of pregnancy. The chances of having triplets once are 1 in 8,000, but twice are 1 in 64 million. Victoria has never used fertility treatments, which boost the probability of having a multiple birth.

The Lasitas had three boys this time round, Casey Alexander, 4lbs 2.5 oz, Caden Bradley, 4lbs 13.5 oz, and Carson Charles, 4lbs 9.5 oz.

Tim Lasita, the father, said everybody seemed to be doing well. He was present during the C-section, along with 18 other medical personnel.

Victoria and Tim have three grown up children from previous marriages. They have been married to each other for 6 years. After their first set of triplets they decided they would like to have one more child – they have now got another three. Victoria said “I guess we should have been more specific and said one more child, not one more set.”

Their first set of triplets were two girls and one boy – Jessica, Jillian and Brian – they have just turned four. They were born after 28 weeks of pregnancy and all weighed in at under 3lbs at birth. Despite some initial lung problems her four-year-old triplets are pretty healthy, says Victoria.

The last time a woman gave birth to her second set of triplets was in New Brunswick, New Jersey, in 2006.

The most common form of multiple birth is two babies, twins (for humans). However, there have been cases of eight babies, octuplets, all being born alive. In 1997 a woman gave birth to octuplets, in Texas, seven of them survived. There have been cases of nonuplets (nine babies) with some being born alive, however, none of them survived for more than a week.
