Are you going to have 2 cars or 1?
Best thing car-wise I did was buying a 308SW as soon as our first was born.

Still Loadsa space for 2 now we have our second and the boot space was larger than a 5-series estate perfect for 2 prams or whatever else.
Reasonably priced, looks decent and you just know that when you or your SO is half cut on sleep deprevation there will be some some kerb rash etc and you wont feel it's a big deal because the car is there for doing the parenting job...
dunno what your budget is like but if you could squeeze in a dedicated family bus then it might mean you also get to have something nice to play around in.
