I have a small child. It's awesome!

It's also enormously stressful and expensive. We're stopping at one where in past times a family like ours might've had 2-3. There are a variety of reasons, but cost in money, time, and housing are big factors. I'm very well off compared to most Americans, so I can see why if you're even marginally on the fence it has tipped into a no.

"Make it work" is a great thing to say on the internet, but not very good advice to people who are one broken down car or health issue away from not making rent, which is a LOT of young Americans.
