I'm also pregnant with my first, so I've been looking at/pondering most of these things as well.
We'd also like to use cloth diapers, but not sure we're going to be able to find a daycare amenable. And I recognize we could just use cloth part time, but if that's the case, I'm not sure it's worth it.
Start a 'daycare' search as soon as you can.
We both worked 3rd shift when our son was born, which is rough without a kid. As her maternity leave drew to a close we were screwed. I had been searching but no one would put up with the hours we worked and going down to one income was going to be too tight, especially with the new medical bills and baby stuff to buy.
I contacted every day care -- too pricey, day hours only, etc... I considered a nanny service -- which would just negate my salary. No family in the area, I contacted co-workers on different shifts, neighbors etc, all dead ends.
We found someone at work whose wife would watch the kid. We thought everything was good until about 10 days before she was to come back to work. She told us she could not do it. In a rush, I answered a lot of craigslist ads, care.com, etc and specifically gave our scenario. From Email, I narrowed things down to 5 possibliities and called each of those and then narrowed it down to two who, out of their home, we willing to accomodate our schedules.
It was a rough go the first few months due to our hours but i managed to get a new job on day shift. Our son still goes there but during 'normal people' hours and it's working out a lot better.. but I had to really push things to find someone.
