I didn't like peapods at all - they were a terrible fit on my little one.

Just a thought - if they are stocked where you work, could you possibly get one of each of the brands that you are considering, and check them out for fit etc?

The itti specials that Raven has spoken of are definately a much better product than peapods IMO.

Ecobubs are great - you can buy just the shell so you can make your own boosters.

Cotton is NOT the greatest nappy fabric, it is not nearly as absorbent as hemp or bamboo.
