How many diapers and wipes of each size?

Kristin
Question for ladies whove already had their twins (or singletons and we will double it!) how many diapers did you guys go through in each size? I'd like to start stock piling diapers and wipes as I'm sure with twins I'm going to go through them like crazy. Plus I'm still working and we have the extra money now whereas it will be tighter when I'm done. But I don't have to buy a bunch of diapers in the wrong size either and waste them.   Any insight would be greatly appreciated!
