When our youngest was born the nurses (incorrectly) thought his blood sugar was low and had him transferred to a different hospital via ambulance. We were able to fight and get the $2000 bill waived on account of the fact that it was a needless trip. Unfortunately my wife spent the night alone as I was with our son.
On a somewhat related note in the span of 10 years the cost to us to deliver our kids doubled. Same hospital too.
