Becoming You, an Olivia Colman-narrated docuseries out Friday on Apple TV+, follows 100 children internationally to show the spectrum of experiences that occur within a human's first five years.Through the eyes of Kiran, who is seen going through a "princess phase" in the exclusive clip below, the viewer learns that "like all children his age, Kiran doesn’t think of himself as having a fixed gender," Colman stated."In his mind, he can switch between being a boy or a girl," Colman added. "For parents, this might seem puzzling as their baby’s sex is usually the first thing they want to know."In the clip, Kiran, based in New York City, happily strolls through the city in his princess costume alongside his supportive parents.
