As a kindergarten teacher, Nick Windschitl knows how to handle little kids.
But he had no experience with children who could fit in the palm of his hand.
Not until August -- when his wife, Sara, gave birth to their twin daughters, Bryn and Nora, three months premature.
Bryn weighed just 1 pound, 4 ounces. Nora weighed 2 pounds. Both were whisked off to the newborn intensive-care unit at Children's Hospital in Minneapolis.
For the next 98 days, Nick and Sara found themselves in an alternative universe they called Preemie Land, where newborn poop was cause for celebration and nurses inserted tiny needles into veins the size of thread.
The Minneapolis couple documented their journey, for friends and strangers alike, in an irreverent and intimate blog (thetwinschitls.wordpress.com), taking readers through the extraordinary world of neonatal medicine and culminating last week, when they finally brought the babies home, just in time for Thanksgiving.
"We have had one heck of a road," said Nick, a shaggy-haired 35-year-old, who once wore a T-shirt at the hospital saying: "I Make Twins, What's Your Superpower?" Now that the girls are home, he said, "we still have to pinch ourselves how lucky we are."
As Nick wrote on the hospital's website last week, "People who don't have preemies probably never think about prematurity ... and people who do never STOP."
