There are loads of fitted nappies out there!
Goodmamas (these are one size and we used them from about 6 weeks)
dunk n fluff
tots bots (cotton tots, bamboozles, stretchies, flexitots)
And thats just a few! They are fine for use under pul wraps, wool wraps (wraps/longies/shorties etc) and fleece soakers/flongies etc. But yes you need a wrap of some sort.
Corssed with stacy!
