This is how I would explain to a little kid what it's like to be trans or non binary.

Okay I've been kicking this around up at work for a while now but this is how I would explain what it's like to be trans to a little kid: some princes were born as a prince and expected to behave as a prince but deep down inside, he would feel more comfortable as a princess instead.

Some princesses were born as a princess and expected to behave as a princess, but just like the prince who would feel more comfortable as a princess, she would feel more comfortable as a prince instead.

For the beans out there: some people were born as a prince or a princess but depending on the person, that might not be correct. You might fall outside of that, or have qualities of both a prince and princess, or even shift between the two. If you don't feel like a prince or a princess at all or kind of feel like a prince or princess but not really, I want you to know that there's nothing wrong with you and you're valid.
