Good for you! I used real diapers for my kids too but it's not very popular in Belize anymore. For the most part, they have been seduced by pampers, etc regardless of cost or environment (no one even calls them nappies or diapers any more - they only call them pampers!) I can vouch for cotton for performance & hemp for coolness but know nothing about bamboo. Good luck to you. Bring some of each and try for youself.
