Question

Why is this show called "All My Children"?

Answer 1

It is the Brotherhood of Man, we are all God's Children. Creator Agnes Nixon wrote a poem that started the show:

The Great and the Least,

The Rich and the Poor,

The Weak and the Strong,

In Sickness and in Health,

In Joy and Sorrow,

In Tragedy and Triumph,

You are ALL MY CHILDREN

Answer 2

It's in the perspective of God. All of God's Children is what it actually means.
