When we had our first, and thus far, only kid there were some complication that resulted in my GF had to be hospitalized. Then it got worse and she was moved to a hospital which specialized in her condition. I moved into the hospital and stayed there for about 2 weeks with her and eventually our newborn son. In the end she was out of her job for almost a year.
Direct monetary cost to us? Zero. The downside is a high income tax so thanks to all my country men for helping us.
Mom, dad and son are all doing great now.
