“In the United States, children have been openly transitioning genders for probably less than a decade, said Jack Drescher, a New York psychiatrist who is a leader in the field of gender orientation. There is very little to go on, scientifically, to support that approach, and the very idea of labeling young children as transgender is shocking to many people.

But to others, it makes perfect sense.

“In children, gender solidifies at about 3 to 6,” explained Patrick Kelly, a psychiatrist with the division of child and adolescent psychiatry at Johns Hopkins Children’s Center.

That’s about the age when girls gravitate to girl things and boys to boy things. It’s when the parents who ban baby dolls or toy guns see their little girl swaddle and cradle a stuffed animal or watch in awe as their boy makes guttural, spitting Mack truck sounds while four-wheeling his toast over his eggs, then uses his string cheese as a sword.”
