We talked about that, and it would mean bad things all around for my family. Background: She's a PhD student and will graduate in May or August.
Option 1) She continues what she's doing right now, research and lab work, and occasionally pick up a shift at a "real" job. However, we wouldn't have health insurance, and that is crucial (pre-existing conditions and baby).
Option 2) She gets a full time job, with benefits. The downside is that we would then need full time daycare for the baby, which is something I am against. Yes, it would only be for a few months, but I think it would be too much for her, since she would essentially be a single mom.
Crazy Option 3) We pick up and move to Cambridge/Mountain View. This would keep the family together, but the logistics of figuring that out while starting a company make my head hurt just thinking about it.
Ultimately, a 3 month separation would be an incredible stressor on our marriage, and that is something I'm not willing to sacrifice.
