Someone wanted Sofia, Lucinda, and Oona to sing this song from Hairspray, so enjoy your request! I thought maybe during The Littlest Princess, The Floating Palace, or Mom's the Word, they could show a little rebellious attitude about getting something they want. (Of course, this is before Sofia gets herself cursed when she brings the Wee Sprites into the castle.)

MIRANDA: Don't contradict me!

QUEEN EMMALINE: Don't disobey me!

MARLA: Don't even think about playing with
those children.

SOFIA, LUCINDA AND OONA: Please!

MOMS: No!

SOFIA, LUCINDA, AND OONA: Mother!

MOMS: Stop!

LUCINDA: Stop telling me what to do

MOMS: Don't!

OONA: Don't treat me like a child of two

MOMS: No!

SOFIA: I know that you want what's best

MOMS: Please!

SOFIA: But mother, please,

GIRLS: Give it a rest!

ALL: Stop! Don't! No! Please!
Stop! Don't! No! Please!
Stop! Don't! No! Please!

SOFIA/LUCINDA/OONA: Mama. I'm a big girl now!

SOFIA: Once upon a time when I was just a kid
You never let me do just what the older kids did
But lose that laundry list of what you won't allow

GIRLS: 'Cause mama, I'm a big girl now

MIRANDA: Oh, Sofia…

LUCINDA: Once upon a time I used to hex my toys
But now I'd rather play with all the girls and boys
So if something happens to me, please don't have a cow

GIRLS: 'Cause mama, I'm a big girl now

OONA: Ma, I gotta tell you that without a doubt
I get my best swimming lessons from you
You're the one who taught me how to "twist and shout"
Because you shout non-stop
And you're so twisted too!
Wo -oh -oh -oh -oh

SOFIA: Once I used to fidget
'Cause I just sat home

OONA: But now I'm just like Gidget
And I gotta get to Rome!

LUCINDA: So say arrivederci!

SOFIA: Toodle-oo!

OONA: And ciao!

GIRLS: 'Cause mama, I'm a big girl now

ALL: Stop! Don't! No! Please!
Stop! Don't! No! Please!
Stop! Don't! No! Please!

SOFIA/LUCINDA/OONA: Mama, I'm a big girl now
(hey mama, say mama)

SOFIA: Once upon a time I was a shy young thing
Could barely walk and talk so much as dance and sing
But let me hit that stage, I wanna take my bow

SOFIA/OONA/LUCINDA: 'Cause mama, I'm a big girl now

OONA: Wo - oh - oh - oh - oh
Once upon a time I used to dress up Sven
But now that I'm a woman, I want human friends
And I don't need Ariel's doll to show me how

GIRLS: 'Cause mama, I'm a big girl now
Ma, you always taught me
What was right from wrong
And now I just wanna give it a try
Mama, I've been in the nest for far too long
So please give a push and mama watch me fly

LUCINDA: Watch me fly

GIRLS: Hey, mama, say mama

OONA: Someday I will meet a human
That you won't condemn

LUCINDA: And I will find some kids
And you can torture them

SOFIA: But let me be a star
Before I take that vow

GIRLS: 'Cause mama, I'm a big girl now

LUCINDA: Oh - Oh - Oh

GIRLS: Mama, I'm a big girl now

OONA: Hey - Hey - Hey

GIRLS: Mama, I'm a big girl

SOFIA: Ooh, such a big, big girl!

GIRLS: I'm a big girl now

ALL: Stop! Don't! No! Please!
Stop! Don't! No! Please!
Stop! Don't! No! Please!

GIRLS: Mama, I'm a big girl now!
