trans | Resources for an elementary school teacher with a possible trans student

My friend from high school is an elementary school teacher. A few weeks ago, she told me about one kid who's "totally going to do that [transition] someday," and described a few classic childhood trans girl moments. (E.g. "When I grow up, I'm going to be a girl.") I tried to get her to look out for the kid, feel out the school counselor, and not assume that the parents know or are accepting. However, she brushed me off, saying that everyone (students and teachers) can tell, and just knows, and looks out for "him".

My friend has since come to her senses a little bit, and now she's asking me for advice:

"Do you have any suggestions on what to talk to him about, how to talk to him about, whether to talk to him about once he's back? He and his classmates are totally open about everything, so I'm sure he'd be fine talking about it. I'm just not sure if it'd be reasonable for me to start with it yet since he is only seven. As someone's who's gone through it, can you give any pearls of wisdom about how I can help him through this the most? I know I'm not the only teacher who's wondering, too, so anything you could tell us all through me would be extremely helpful!"

Her only frame of reference is me, who's transitioning, so you can see her questions are kind of skewed in that direction. I know nothing about helping trans kids (beyond what I wish people had done for me, which is obviously my own personal experience). What can I tell her so she can help this kid safely explore hir feelings, and transition if its right for hir?

In addition, any Washington D.C.-area resources would be great.
