Dear Jack,
There’s the near daily discussion between Mommy and I about the possibility, in the future, at least a year from now, of us possibly trying to have another baby. Yes, that would mean a younger brother or sister for you.
We can easily think of good reasons we would want you to be an only child. We can also easily think of good reasons for you to have a sibling.
As far as why you should have a sibling, there’s one weird reason that keeps popping up in my head; one that Mommy has never mentioned.
So I guess I have to file it in the “Daddy’s Deep Thoughts” folder. Here it is:
I think about all the potential siblings who would never be born if we just stopped with you.
It just seems weird to only have one more. Why not two more? Why not five? Why not ten?
At some point for financial, logistical, and other practical reasons, that “one more kid” finally becomes one too many.
How am I supposed to know who the final little brother or sister is supposed to be?
Half of me is wired like Jim Bob Duggar, while the other half is wired like every parent in the history of the world who was content with their decision to only have one child.
I mean, to a certain degree, God leaves it up to Mommy and I to decide how many more lives to bring into the existence of this world.
Really? God is okay with my input in that decision?
No matter how many (or few!) brothers or sisters you end up having, or not having at all, much of that responsibility falls on your parents.
We have less than a decade to decide…for us, for you, and for all the siblings who will never exist.
Love,
Daddy
