sounds pretty good when you play along. Enjoy!

Intro D G x4
Verse 1

D	        G           D
As a small baby Each time I cried
   Bm     A       G
My mother came to me
D		   G           D
To ease my worries and calm my fears
Bm	     A    G
with a sweet melody
Bm		       A
I remember hearing the sound of her voice
     G	                         A
As I screamed in my drool and my pee
      D
She'd slug back some whiskey
G	   D
light up a smoke
    Bm     A       G A
and gently sing to me

Chorus:
       D
Go to sleep little leech
    G           D
You sucked mama dry

Made her more crazy
     A
With every cry
    D
Why weren't we more careful
     G	           Bm  G
that night on the beach
      D
Go to sleep
      A            D
Go to sleep little leech

D G x2

Verse 2:
I grew into a terrible teen
And ate all of my parents food
Stole all their liquor, broke their antiques
Wore stupid clothes and was rude
One night I drove the car home
Covered in vomit and missing a door
But my dad didn't yell he just smiled and he said
"Son you don't live here no more!"

Chorus:
Go to sleep little leech, you've sucked us bone dry
Stolen our money and will to survive
But youre old enough to kick out on the street
Go to sleep, go to sleep little leech
(go to sleep.. go to sleep)

D G x6

Verse 3:
Now I'm a father with my own child
Who screams and screams and screams
He screams and screams and screams and screams
and screams and screams and screams and screams!
I'm up at 11, at 2 and 4
And all I can do is yell is WHY?
And I swear that I hear my mom laughing at me
As I sing that lullaby

Chorus:
Go to sleep little leech, you’re driving me mad
Sometimes I dream that I'm not your real dad
It's 5 in the morning I work in the day
Go to sleep little leech or get sold on ebay

N.C
Go to sleep little leech everyone tells
				        A
me your an angel, but I know youre from hell
    D			           G	       Bm    G
How else could 9 pounds six ounces make such a screech?
      D		   A
Go to sleep, go to sleep
      Bm	       G
Go to sleep you little creep
		     A
I beseech ye! Little leechy
        D G till end
(go to sleep.... go to sleep)

Go to sleep
