Hi - does anyone have a neppula nappy? Have read a few good things about them and the designs are pretty funky.... So - thinking of getting one for Dylan but not sure on the size. The weight guidelines are medium - 6-10kg, large 8-16kg and med/long - 8-16kg. Says high on rise so to go down a size with skinyn babies. Dylan is skinny and about 11kg's but not sure if thats too beg for a medium.... Anyone?
