I've used the nappies - they're brilliant! Was especially impressed because they even do a micro size, perfect for Noah at the moment.
Only con (and it's a very teeny tiny one) is that they're just plain white with no design to show you where the front is, so a few times I've ended up putting them under Noah the wrong way, resulting in me having to turn it round the right way and then being peed/pooed on!
