If you have to!

This is a poem I wrote when I was pining to have a baby in 1991.

Little darling!
Song of my life!
Don't tug so hard
at the strings that hold me together.
Sweet child!
My very own!
You will arrive when you have to
If you have to.

All my decisions are futile
My courage, my ruthlessness, my cruelty
And so is
this persistent craving.
Sweetest one!
Elusive flower of my garden!
You will come when you have to
If you have to.
