There are various solutions for biking with an infant, and from what I can tell, a c-section takes 6-8 weeks for recovery. No one ever side bikes should be the only possible form for transport. Use the car for 2 months while your wife recovers, for the trips she needs to take. If you live in a walkable area, go for a walk.
A bike path is easier to drop in than rebuilding entire cites and relocating the entire population around those walkable areas. Bike paths take years, consolidating urban sprawl would take decades, even if the political will existed.
Of course, I can also drive almost anywhere with them.
