A/N: This is a short songfic based on Taylor Swift's Never Grow Up. The idea just randomly popped into my head as I was listening to this song on my way home from university. It's just a whole lot of fluff… I hope you like it and I hope that weird speech bubble thingy to review isn't too hard to push… Please? ;-)

Disclaimer: NCIS still isn't mine. Never will be.

Your little hand's wrapped around my finger
And it's so quiet in the world tonight

There he is sitting, holding his daughter in his arms for the first time. The moment that his girlfriend had told him that she was pregnant, Tony had hoped that it would be a girl. A girl he would be able to spoil. And there she is, little Mia DiNozzo. He smiles.

Your little eyelids flutter cause you're dreaming
So I tuck you in, turn on your favorite night light

He carefully tries to push a strand of hair out of her face in order not to wake her. She's been sick for nearly a week now and Tony has been worrying like crazy. He would give anything in the world to make her feel better. But for now she's sleeping and the proud papa silently hums Hush, little baby.

To you everything's funny, you got nothing to regret
I'd give all I have, honey
If you could stay like that

She's sitting in the sandpit in their garden. She's laughing whenever the mountain of sand, that she is trying to build, is collapsing. Tony keeps her company. Occasionally, he would let the sand flutter on his head just to make her laugh. It works every time. Tony is laughing along with Mia.

Oh darling, don't you ever grow up
Don't you ever grow up, just stay this little
Oh darling, don't you ever grow up
Don't you ever grow up, it could stay this simple

He wishes she would stay four years old her whole life. Everything seems to be so easy. When he picks her up, playing with her, he always gets a smile in return. Then everything is okay. For her and for him.

I won't let nobody hurt you, won't let no one break your heart
And no one will desert you
Just try to never grow up, never grow up

He is going to kill that guy. His little Mia has a date. It's far too early. Isn't thirty the right age to see boys for the first time? He sighs, at least, she has told him. It could be worse. He smiles as he watches her getting dressed for the fourth time.

You're in the car on the way to the movies
And you're mortified your mom's dropping you off
At 14 there's just so much you can't do
And you can't wait to move out someday and call your own shots
But don't make her drop you off around the block
Remember that she's getting older, too

He can see the look on Ziva's face as she lets Mia hop into the car. She's driving her to the date. Tony gives his wife an encouraging smile hoping that Ziva is thinking the same thing as he does. It'll work out.

And don't lose the way that you dance around in your PJ's getting ready for school
Oh darling, don't you ever grow up
Don't you ever grow up, just stay this little
Oh darling, don't you ever grow up
Don't you ever grow up, it could stay this simple
No one's ever burned you, nothing's ever left you scarred
And even though you want to, just try to never grow up

Tony and Ziva are flipping through some old pictures. Little Mia, aged 7, in pink Snoopy-PJ's waving into the camera, having a big smile on her face. Tony looks at Ziva and smiles. Time sometimes goes by too fast.

Take pictures in your mind of your childhood room
Memorize what it sounded like when your dad gets home
Remember the footsteps, remember the words said
And all your little brother's favorite songs
I just realized everything I have is someday gonna be gone

Tony watches his little kid standing in her room, looking a little forlorn. Moving boxes are standing everywhere. He just can't believe she's moving out to go to college. Where has his little girl gone? He can hear her hum, then sing. Hush, little baby don't say a word, papa's gonna by you a Thunderbird. She turns around and smiles at him.

So here I am in my new apartment
In a big city, they just dropped me off
It's so much colder that I thought it would be
So I tuck myself in and turn my night light on

Mia is watching her father leave. She tries to be brave but she can feel her tears already sting in her eyes. As her dad is almost out the door, he plugs in her old nightlight with the moon and the stars. He turns around one last time, smiling sadly. She returns the smile, hoping it says everything she wants to say to him. He just nods and then he's gone.

Wish I'd never grown up
I wish I'd never grown up
