Dear Prudence,
I have two kids. My oldest, a middle-schooler, is transgender and has been living as a boy since kindergarten. My youngest, who is in elementary school, was adopted into our family after my oldest transitioned. We never sat her down to explain her brother’s gender identity to her, and I don’t believe they have discussed it among themselves. I don’t know if or when to talk to her about this. I have let my son take the lead on who he wants to tell outside the family, but what about inside the family?
