Check out 'for sale' on here, and post a 'wanted', and you might find some nappies.
Th fleece wraps - apparently, some of the moisture passes through and is evaporated, so the nappy inside does not get quite so wet as it would in a PUL wrap. They say that if baby is sitting in one spot for a long time (eg in a car seat) the moisture wont be able to evaporate off, so it will wick out onto clothes. BUT, My DS lies in the same place, on his tummy, all night, and there is no wettness under him, so I don't get it!
I have 2 fleece wraps, and one PUL. I prefer the fleece - his nappy is absolutely sodden under a PUL, and very wet, but not dripping under a fleece. They do stink though!
The tots red wraps are very thick (the coloured ones are not as thick, sadly, although a friend of mines uses them with sucess, but her baby is younger, so less wee!). Another thick brand is 'stacinator' - don't have one, but apparently they are good at night too. Tots have velcro, and stacinator have poppers.
If I was organised and washed as often as I should, 3 wraps and 4 nappies would be enough I think. I have 5 nappies and 3 wraps, and sometimes run ot and use a disposable at night, but once in a while doesn't realy bother me. It seems the more nappes I buy, the less I wash, so it doesn't really help!
The fleece wraps do smell, but you can use them a few nights in a row if you can stand it! Otherwise you can rinse them under the tap and hang to dry, or out them through a rince cycle and dry. My friend washes them in her older DCs bathwater!
