I really like my stash and just in time for her to PT this summer no doubt lol.
I like to have two systems as i like different nappies for different needs/occasions - for this reason i have more than a full stash of fitteds AND pockets/AIO's hehe - i can go close to 2wks without washing lo (not that i ever would!) I love F&S and HL fitteds for use under wool & wraps - i only use DnF wraps as these are my faves...
Pocket wise i love WNSS and my WNOS now shes on the largest rise and i dont need to worry about the rise poppers becoming undone lol. Also like a few Itti AIOs and BBSS thrown in too, for variety.
I have various other brands too, but those would be my 'core' stash.
The only thing i think i would do, if money permitted would be to have many... MANY more woollies! Tho we have a lovely stash, you cant have too many woollies hehe
