> I think a more humane (and likely more successful) way out of this is to not try to convince the childless to have children at all, but to try to convince those with children to have more.

> So, I'll pose this question to HN and see what you all say: If you have kids, why not more? (if you're too old/young, just imagine you're the right age)

> I'll go first: We'd both like to have more kids, but we honestly don't have the time for another. They really do eat up loads of your time.

I think you've largely answered your own question, by reflecting on your own circumstances. I suspect there are plenty of people who would not mind having more kids per se, but simply cannot afford to (in terms of time, or in terms of money, etc).

We are planning on a second kiddo, and I can barely fathom how we'll make it work with what little time we have left. At least in the US, we simply don't have a society that makes it easy or feasible to have kids - financially or otherwise.
