If you look on my blog you can see exactly what I have for Peanut's stash. We will mainly be using fitteds so have a load of Tots Bots stretchy bamboozles on the way, as well as some xs basics from the US, as they have a snap down tummy for the umbilical cord. We use PUL wraps in the day and fleece at night.
We do have some Teenyfits for ease of use when out and about, and 'cos they are so cute!
Once he has outgrown his early stash, we'll replace them pretty much like for like (size two bamboozles, which are really BTP) and Easyfits (which again, are pretty much BTP, and which we have loads of for our daughter anyway).
We chose the ones we have based on performance, drying times and expense - we just don't have the funds for the wahm made fancy fitteds (and I'm one of those who begrdudge paying a fortune for a nappy that doesn't really do the job any better just because it looks nicer, especially if it's a fitted that gets covered up by a wrap!!!!
