With miss M - I think I started full time cloth when she was 2 weeks old ... and i used prefolds and a great cover. I also used newborn fitted nappies, various brands, kissaluvs fitted (which are GREAT).. umm... itti bittis... sized bumgenius... but I'm wary of using AIO's or something like that for newborn poop.. yukko.. best to have a fitted and cover (I'm not very good with flats, they are always so HUGE on DD - I use them on DS though)
