<human>: Provide a brief overview of the text.

My wife of two years (been together 12) recently became pregnant by accident and miscarried very early on. Previously, we had never seriously considered children - talked about it yes, but it was only talk. Now we both kind of feel like the door has been opened and we need to figure out if we want to have a kid. I'm 34 and she's 29, we figure it's kind of now or never. 

We have enough money and all that, which is to say, apart from loss of "freedom" we can afford to do it. Problem is I can't decide if I want one. The only valid arguments for having a child are "I would never look back, it's been the most wonderful/challenging experience" - but is this merely after the fact rationalization? I should state that there are many arguments for having kids, but they're not solid, apart from the one: they change your life in unimaginable ways.

Am I missing anything in my calculations, or is the only evidence kids are fun to have presented by those with kids? Those for whom it is too late to revert.
<bot>: Not sure if I/we should have kids as the only testimony of the excellence of kids comes from those who are stuck with them already.
