Rebecca, you know I have mixed race daughters too who are somewhat older than your daughter. I had hoped with increasing awareness of racism that these situations would have reduced, but reading your story it obviously hasn’t. I’m so sorry your daughter had to experience this but unfortunately it was inevitable.
My advice is to watch her mood carefully, wounds like this go deeper than we think and affect our children psychologically. Their confidence is affected and they start to question their identity “I’m obviously not white enough to be treated as white, but am I Black but not black enough?”
At 15 my older daughter hit a psychological crisis, I believe that this was triggered by instances of racism that she did not share with us until many years later.
I will pray for you and your daughter 🙏🏾❤️
