Here's a little ditty I made with my 4 year old daughter.  She loves to sing about three things. Princesses, babies, and potty. Here is a song that features one and a half of those things.  

Hope you enjoy.  

Lyrics:

My favorite food is cake and cupcakes
But I have to eat my dinner before that

I like to eat, chicken and rice
But, you're not my favorite chicken to eat

Chicken, chicken, chicken
You're so greasy...I love you

Chicken, chicken, chicken
You're so greasy...I love you

Chicken, chicken, chicken
You're so greasy...I love you

Chicken, chicken, chicken
I love you forever

I sing a princess song...

Potty ... Thunder poop
All the time.....Thunder Potty

Potty ... Thunder poop
All the time.....Oh no, it's emergency potty

I gotta go, gotta go, gotta go
Thunder poop
When I'm doin' my special poop dance

I gotta go, gotta go, gotta go
Thunder potty
When I'm doin' my special poop dance

Listen to everything I say

You have to go potty in the bathroom

Then you wipe your butt

N' then flush the toilet

And wash your hands

I wash my hands 
And then I dance around
I wash my hands

I wash my hands 
And then I dance around
On the floor

You have to go potty
You have to potty

You have to go potty
You have to potty

You have to go potty
You have to potty, potty, potty, potty, pahhhhhteeeee

Potty ... Thunder poop
All the time.....Thunder Potty

Potty ... Thunder poop
All the time.....Thunder Potty

etc.
