They can't possibly expect you to actually pay anything like that, can they? I think for having our first kid (including well regarded obstetrician and a two week stay in the NICU) we paid a total of around $5k. Three cheers for civilized countries with real healthcare!
Not to mention the way they over-serviced you sounds downright exploitative. I wonder if the staff had been covertly told to use as many consumables as possible?
