Not flesh of my flesh

I was reading a book for the community yesterday and found this. 

Loved this poem and the spirit of it. 

It is anonymous and is often given to children by their adoptive parents. 

It is called The Answer. 

Not flesh of my flesh, 
Not bone of my bone,
But you are the child
I will call my own.
Never forget for a minute - 
You grew not under my heart
But in it.

Not flesh of my flesh,
Nor bone of my bone,
But still miraculously my own.
Don't forget for a single minute, 
You grew not under my heart 
But in it.

Not flesh of my flesh,
Nor bone of my bone.
But still undeniably my own.
Never forget, for even a minute,
You grew not under my heart,
But in it.
