Little baby, if you're reading this
You're probably all grown, the way most babies do
I'm sure your eyes are still that pretty blue

I'm writing to you from 1991
The year I gave you to a mama with a girl and son

Dm           Am      C         G
Please don't look at this like a hit and run
Dm      Am             C                G
In a breath I felt you leaving like the setting sun
Dm        Am            C                G
Life just thought that I should draw the short straw
Dm         Am           C                 G          (then back to the verse pattern)
But little baby, for a short time I had you to break my fall
Fall, fall

(Repeat verse pattern F | C | Am | G)
Your new daddy, yeah, he loves you too
To the moon and back, he said
When I laid you in his arms
And he kissed your soft blonde head

Dm           Am      C         G
Please don't look at this like a hit and run
Dm      Am             C                G
In a breath I felt you leaving like the setting sun
Dm        Am            C                G
Life just thought that I should draw the short straw
Dm         Am           C                 G          (then back to the verse pattern)
But little baby, for a short time I had you to break my fall
Fall, fall

C        G     Am
Your new family knows
C        G     Am
I did this all for you
C               G
Maybe one day, you'll believe it too
