On the other hand, if there was a clear way to distinguish the guevedoces from the "permanent" girls before puberty, then they would presumably raise them as boys, not girls, because they would know that the penis is going to eventually come in. But their descriptions of discomfort with girlhood don't sound that much different than the ones I had, and so the parents can't tell them apart from any other persistent tomboy. Traditional girlhood is not a positive experience, it is designed to shape children for a subservient adult role. It is not strange or unusual to hate it and it's not evidence that someone is secretly a boy.
