As always, timing is everything.

My husband and I recently discussed the idea of having another child. Louie had turned a year old, if memory serves. It wasn't an "if," it was "when." That much helps when you can agree on that, let me tell you.
I had joked before that when we had a fourth, I'd want to have another rather quickly so that child would have someone to play with. I was half-kidding; I didn't know how I'd deal with four, so it was all theoretical.
Well, I opened the discussion. I didn't expect him to have immediate answers and he didn't. I basically wanted to make sure we had all of the pertinent information. Like that I'm 38 this year and he's 40. The clock is ticking and the risks go up perceptibly with each year. However, we live in an already crowded house and have extremely poor prospects for selling it. We have no control over the real estate market and less of an idea on when it might shift; under what circumstances did we just damn the torpedoes and go for it anyway?
He didn't have an answer. Neither did I, but I put it out there. "I just want the discussion to be open," I said.

We forgot something, though. We have a third Person in our marriage, a "silent Partner" as it were. He had an answer.

The answer is... October.
