I feel woefully inaqdequete to comment as I only have Tots, Bamboozles Nature Babies pockets, Stuffies and Little Lambs (actually that sounds more than I thought) but I still love the little size 1 white cotton Tots Bots, as they look so perfect and pure on a tiny bottom.
My favourite nappies are my Stuffies. They are only made to order now which is no bad thing as you can practically design them, but they are cute, colourful and versatile as you can adjust the stuffing to suit. Plus the fleecy inner is practically indestructible to those nasties.
My best buy were the Little Lambs as they were free
My worst buy are the Nature Babies one size pockets as they either don't fit, or just don't work, so I never use them (anyone want them? lol
