We use a liner just through the crotch area though which is why I think it's the nappy as the rash is only occuring where it's directly touching her skin, ie waist, thighs and hips (and not where the cover is touching - thanks Deb

) , so have considered making a giant nappy shaped insert. The covers I'm using are TotsBots, Bummis and I have 1 woollen soaker (though not yet using the ones my Mum knitted shhh.....

).
Bobbie did I read that Rowan suffers from excema as well (great name by the way

)?
