One thing would be that you miss the birth.
We live in the Mountains near Boulder, this is a very friendly midwife town. The town stats [no cite] are ridiculously high for healthy home births. Luckily the birthing center we are attached to with our insurance is very, very good, possibly best in Colorado. Many women have midwives, and the center is located in the hospital’s parking lot.
I’m not too worried. I am looking forward to walking with my wife during labor, looking at the mountains, playing a little Ben Folds, and other music, getting in the tub, and just being in a climate and location that is very familiar. The reduction of stress is incredibly helpful during birth and our midwife is all about the low stress!
