(ABC NEWS) The McCaughey residence in Carlisle, Iowa, is home to the famous McCaughey septuplets.

The siblings made history in 1997 when they became the first set of septuplets to survive infancy. When they came home, the septuplets, their parents, Kenny and Bobbi, and their big sister Mikayla, settled into a life of diapers, bottles and birthday cake — all multiplied by seven.

And today, all seven of them — Kenny, Alexis, Natalie, Kelsey, Nathan, Brandon and Joel — are turning 16.
