My sweet niece is 2 days old today, but she does have a name - Josephine Grace! This is from Songs of Innocence, as you may have guessed.
Infant Joy
By William Grace
"I have no name:
I am but two days old."
What shall I call thee?
"I happy am,
Joy is my name."
Sweet joy befall thee!
Pretty joy!
Sweet joy but two days old,
Sweet joy I call thee:
Thou dost smile,
I sing the while,
Sweet joy befall thee!
