Then They Do by Trace Adkins (I must be odd as I never wish Noah would grow up quick)

In the early rush of morning
Trying to get the kids to school
One's hanging on my shirttail
Another's locked up
In her room
And I'm yelling up the stairs
Stop worrying 'bout your hair
You look fine

Then they're fightin' in the backseat
I'm playing referee
Now someone's gotta go
The moment that we leave
And everybody's late
I swear that I can't wait
'Till they grow up

(Chorus) Then they do
And that's how it is
It's just quiet in the morning
Can't believe
How much you miss
All they do
And all they did
You want all the dreams
They dreamed of
To come true
Then they do

Now the youngest is starting college
She'll be leavin' in the Fall
And Brianna's latest boyfriend
Called to ask if we could talk
And I got the impression
That he's about to pop the question any day

I look over at their pictures
Sittin' in their frames
I see them as babies
I guess that'll never change
You pray all their lives
That someday they will find happiness

(Chorus)

No more Monday PTA's
No carpools
Or soccer games
Your work is done
Now you've got time
That's all your own
You've been waitin' for so long
For those days to come

(Chorus)
