[Verse 1]
 
D
She's got a smile that it seems to me
  C
Reminds me of childhood memories
       G
Where everything
                                D
Was as fresh as a bright blue sky
D
Now and then when I see her face
    C
She takes me away to that special place
         G
And if I stared too long
                              D
I'd probably break down and cry

[Chorus]
 
A               C              D
Whoa Oh, Sweet child o' mine
A               C              D
Whoa, Oh, Oh, Oh Sweet love o' mine
