I BF and used reusables. Neither exclusively (well, bf initially but then shared as I couldn't get enough expressed for creche - but we shared until 9 months). Creche also wouldn't use reusables (DD went into creche at 3 months) as too much hassle. That was fine as it WAS a lot of hassle for me too!!
I did it mostly for environmental reasons, and admittedly the new reusables are a LOT easier than the old terry squares my mum had used (and she also wasn't exclusive).
But at the same time, it wasn't that hard, when I was already doing a fair amount of washing and the nappies could go on the line.
BF was for trying to do my best for DD, convenience, and it's what I was used to seeing at home (at least initially - there were bottles at some point).
If I was asked, I would say what we were doing, and if someone was interested, I'd show them the nappies. But I certainly never was evangelistic about them - each to their own.
(That siad, I know a good few who were VERY strong on bf, reusables, growing own veg and using organic food, lots of them were veggie too - whereas I enjoy a good steak, grow some veg but shower it in slug pellets to get to eat some of it, only buy organic on occasion, will drink plenty of red wine with my steak, and know I make lots and lots of mistakes among the occasional things I do right for DD and the big wide world! Oh, and I bought a car after DD was born and now drive everywhere when I used to be the queen of public transport - so there is definite ofsetting of my good efforts going on!
