Is it possible that they are wicking a little as well? I dont really know a great deal about these nappies though- but I have heard good things about the Happy Heinys one size nappy and they seem to be a similar idea. I know a lot of people have problems with MCN with newborns for this reason. Most people seem to find flats the most effective while they are newborns at least until they are over the 4-5kg mark. I can understand your frustration with your DH using the disposables.... no suggestions bar it wont be long until your bubba fits into them well.
