Even before their birth 18 years ago, the odds were against the McCaughey septuplets.
With their weights ranging from just 1.04kg to 1.4kg, the likelihood of them all surviving wasn’t high.
The chances of them all making it to their high school graduation even less likely.
Yet, they’ve beaten the stats to not only become the world’s first surviving septuplets – but to also graduate high school.
Alexis, Brandon, Joel, Kelsey, Kenny, Natalie and Nathan McCaughey all crossed the stage on Sunday as part of Carlisle High School’s class of 2016.
The septuplets were born on November 19, 1997, after their mother had taken a fertility drug.
According to KCCI-TV in Des Moines, the septuplets are going on separate paths following high school, including the military and college.
The station says two of the seven plan to attend Hannibal-LaGrange University in Missouri, where their parents say they were promised a free education.
When you see the photos from when they were first born (above), it really is an achievement to be celebrated!
