No they were sized: a range of small and mediums that saw Jazz from 4kg to 14kg (she was a very big baby at 1yo!). We used itti bittis since she was 1yo just because I could afford to and they were cute (we bought the fitteds because they were ebay cheapies, which was all we could afford at the time, but they worked fine. Not as great as 'MCN' but does the same job. Not as absorbant, but they were cotton, not bamboo or hemp). Itti bitti have brought out a OSFA recently, which we are considering using for our next bub. I think they are called tutto's?
