Not quite identical twins.

From the Boston Globe:

Led by the child who simply knew

The twin boys were identical in every way but one. Wyatt was a girl to the core, and now lives as one, with the help of a brave, loving family and a path-breaking doctor’s care.

Jonas and Wyatt Maines were born identical twins, but from the start each had a distinct personality.

Jonas was all boy. He loved Spiderman, action figures, pirates, and swords.

Wyatt favored pink tutus and beads. At 4, he insisted on a Barbie birthday cake and had a thing for mermaids. On Halloween, Jonas was Buzz Lightyear. Wyatt wanted to be a princess; his mother compromised on a prince costume.

Once, when Wyatt appeared in a sequin shirt and his mother’s heels, his father said: “You don’t want to wear that.’’

“Yes, I do,’’ Wyatt replied.

“Dad, you might as well face it,’’ Wayne recalls Jonas saying. “You have a son and a daughter.’’

That early declaration marked, as much as any one moment could, the beginning of a journey that few have taken, one the Maineses themselves couldn’t have imagined until it was theirs. The process of remaking a family of identical twin boys into a family with one boy and one girl has been heartbreaking and harrowing and, in the end, inspiring - a lesson in the courage of a child, a child who led them, and in the transformational power of love.
