The big win is "suburb", but also consider smaller cities. Suburbs can be OK for city dwellers who have cars, which isn't all of them. The daily commute runs backwards of the norm, so traffic is reduced for them. Smaller cities are really affordable. You can pay people less and they still get bigger houses.

Keeping work tasks at the workplace is important. There is an extra benefit for you: security. The best practice is to store proprietary stuff on a network that isn't connected to the Internet at all. Instead of suspending email delivery, just deliver it exclusively to devices at the office.

Babies at work is important if you hope to keep mothers. Nursing works best when there is no delay. The problem with special rooms for nursing is that they create the expectation that they will be used, but nursing is far easier if people are comfortable nursing wherever they happen to be at the moment.

If you can do flex-time, do it. (depends on nature of business) I'm at a place where some people come in randomly, some come in before the Sun is up, and others come in in the late afternoon. Missing a day entirely isn't a big deal; you just make it up. (we do timecards) I'm sure this helps non-parents too: some people want to take college classes, some people want to go surfing, etc.

Timecards may be helpful. Without them, people may feel pressured to work unreasonable hours.
