Thanks Gigi - thats wonderful to hear. As they are not cheap, its great to know that not so many sizes are needed. I think getting them for a night cover will be good - Id rather buy these disana ones over making my own if the design is so good as you discribed. I have been reading that wool works well for night, but when I told DH he was doubtful. What do you use as the nappy? Do you have something different for day and night?

Now I just need to find someone who has used the disana nappy and see if they think a PUL wrap cover will work during the day over them - Im still concerned that the nappy design itself may be bulky too and only suit the disana style over pants.
I think they are a lovely looking product and not at all badly priced, but if we get them we might mix them up with a few babybeehinds or simialr as well....?
