Grown - A Haiku

The other day while suffering through adds on Hulu, I caught a statement that struck me to the heart. It was "one day you will put your child down for the last time and not even know it." 
Just thinking about that made my heart ache, so I poured my pain into the following poem, made up of haikus:

Grown

Up into my arms,
Your weight settled, face alight,
Eyes dancing with fireflies.

I kissed your forehead
And held you tight to my chest
Like part of myself.

You fought me, laughing,
As if you truly wanted 
Me to let you go.

You looked up at me
And placed your hand on my cheek;
I let my guard down. 

My grip on you slipped,
Grinning like a small devil,
You sought your freedom.

When did you grow up,
Learn everything that I know,
And all that I don’t?

You leaped from my arms,
I didn’t know this was the last time
​I would hold my child.
