First Giggle

The radio was playing blues;
I danced and in my arms
My 3 month grandson focused on
Exuding all his charms.

But suddenly to my surprise
A brand-new trick emerged - 
A flat-out giggle, loud and clear
And oh, my heart just surged.

He giggled then a bunch more times
So his intent was clear - 
The music and the movement
Set his giggle track in gear.

I will not witness all his firsts
But this one was a thrill,
For laughter is a trait of which
I'll never get my fill.
