I found this today and it is perfect in every way.  This really summarizes the power of being a mother, even in a bi (or even tri) racial family. 

What can I teach you about being Black?
Not much,
Because I'm not.
But I can teach you about pain,
And how to forgive peoples foolish words.
I can show you how to endure suffering,
So that through it Truth will be proclaimed.
I can love you and cry with you,
I can be the she-bear when you are threatened.
We can live where there is a rainbow of people,
and we can learn to love them together.
We can seek out the truth of history,
And not be afraid of the ugliness.
I can open your heart and your eyes
To the painful reality that comes clinging to the back of sin.
And in the end, I can release you into your destiny,
And wait for you to come home,
With a fuller understanding of who you are
and what you are to be in your life.
Then I can listen as you teach me,
What it means to be Black.
