SPOILER: Given that this was originally written as a play, it may be unavoidable that most of the story is of the adults. Jake's father is a Freudian-style psychologist, and there is a fair degree of filler as he repeatedly meets with a client. Jake's mother has had ballet training, had worked as a lawyer, but dropped out to be a full-time mother, to the disapproval of HER mother.
Filled with fairy tales read by his mother, there is little attempt by either parent to "correct" Jake's non-gender-conforming behavior - wearing dresses, playing the role of princess. Even at a queer-friendly pre-school, there are signs of trouble. Things get worse when the parents try to place Jake in a private kindergarten, where trial placements often end up with verbal abuse and fights.
The entire story happens over maybe 8 months, so there is no answer to the question as to whether Jake grows out non-conforming behavior, or actually identifies as a girl. I did note that Jake's last scene had him wearing not a dress but a tutu. Was it all simply his mother's influence?
