More Heart than Most

My son has more heart in his half a heart than most men with a normal heart

Born with half, yet more to give,
A tiny heart that chose to live.
Smaller chambers, but fierce and bright,
A soul that burns with boundless light.

Half a heart, yet whole in might,
Stronger than most in every fight.
Each beat a testament, brave and true,
A lifetime of love contained in few.

Not measured by what others start,
But by the courage in his heart.
Though halves compose his fragile part,
He carries more heart than most in whole hearts impart.
