The last time I felt this way was after my daughter, Kai, began asserting her identity at just 18 months old. Our story is similar to that of so many other families blessed to raise transgender youth. From almost the beginning, she told us who she was, fashioning her t-shirts into dresses and becoming obsessed with Disney princesses. At first I thought that she was gay, until I slowly came to the realization that God had given me a baby girl, not a boy.
