For day use our most absorbant fitted nappies are - Flutterby fluff, Upsy daisy fitteds, baby beehinds, WNNL.
As for pockets I use BBOS aplix and WNOS aplix I use them with petit desous bamboo inserts and a hemp booster.
Nights I use - Flutterby fluff night nappies Upsydaisy Night nappies and WNNN.
I use wool over my fitted nappies. I never get any leaks.
I only currenly have 1 UD fitted but I do find it one of my more absorbant nappies. I will have to get saving the PP to get a couple more. Mine I dye and paint myself.
