1. You're assuming there is a decision made by US couples / women about whether to have a child based on income. I don't think that conscious decision happens very often, I think there's a whole bunch of people who convince themselves they'll "get by" because reproduction is a basic drive. Fertility rate therefore would not be much affected by the level of family support, but the quality of life for the individuals concerned very much would be. It's that quality of life that I was trying to highlight.

2. I am in the valley. I work for Apple, and 9 years ago when the kid was born, Apple's policy on paternal leave was in fact 2 weeks paid leave, you could opt to use your vacation (which I did) after those 2 weeks, and you could cash in a week's accrued sick leave as well as a bonus if you had it, but that was it. It's better now, but that doesn't make my experience any different.

2(a) My wife worked for Chevron at the time, and their policy (who knows what it is now) was similarly 2 weeks of paid leave, then you can take accrued vacation, then you're back at work. She quit.

Reading back my original post, I can see it's confusing where I'm saying "I" and talking about being in hospital - I was trying to continue the "My sister":"Me" but it was of course my wife giving birth, not me.
