In all honestly, I dont rate any nappy survey.
Its a nice overall generalistion but htere are so many variables - not the least of which is the babys body shape.
Even in disposables, some people swear by one brand while others have nothing but problems with them.
The MCN test are pretty useless as they compare different kinds of nappies with each other, althogh the IB AIO v AI2 at least is within the same brand.
