I trialed a Bambooty for Cheeks&Cherries and they are a really slim cute nappy. They have a sort of cradle inside which keeps poo from escaping and are really absorbent. They look really tiny at first like Itti's as they are a low rise nappy. They come with a handy little wetbag too, which I have taken damp wipes out in with no leaks.
I have two large Bambootys for 15 month old dd. They took a few pre-washes to get to the right level of absorbancy and where DD is such a skinny minny the waist gaped a bit when I first tried them (and she was 22lbs). However now she's put on a bit more weight they work a treat. I have one of each type. Also got mine from Cheeks and Cherries.
