I like the BBH OSFA a lot and I wish I had more of them! I like the bamboo more than the hemp cos the hemp tends to feel very rough (or maybe it is just the way I wash it!) whereas the bamboo feels softer. They are really not that hard and if you put the boosters in when they have been washed it is even easier! It only takes a couple of seconds to pop the cover on. The only thing is they are snaps and not velcro so that takes a bit longer to do them up. Maybe get a few AIO for DF and the rest can be OSFA? I presume you will be doing most of the nappy changes anyway? OSFA is cheaper too cos they can do one baby the whole way rather than needing to buy sized options.
