It was a joyous time as the world's first surviving septuplets celebrated their 13th birthday recently.
Kenny, Alexis, Natalie, Kelsey, Nathan, Brandon and Joel McCaughey were born to Bobbi and Kenny McCaughey, devout Christians from Carlisle, Iowa, on November 19, 1997.
Doctors had suggested that it would be impossible for the septuplets, who were conceived after their mum took a fertility drug, to survive past their first birthday.
But they have beaten the odds and the three girls and four boys all look a picture of health today.
"It isn't a joke when people say enjoy them, because it happens so quickly," the Daily Mail quoted Bobbi as saying during a preview for an interview on NBC documentary America's Septuplets Turn 13.
"Sometimes you think it will last forever and that there will be another tomorrow just like this, but it is not. It changes so fast," she said.
During the early months, the septuplets drank 42 bottles a day and used up 52 nappies, and these days, the family spends 300 dollars a month on groceries, shopping at food warehouses and growing their own produce.
According to People magazine, they also do 10 loads of laundry per week and they have two refrigerators, two dishwashers and two freezers.
Looking at them today, the teens are very adept at helping around the house.
"They've gotten to be such good helpers. They all do their own laundry," Bobbi added.
