Popsy said most of what I was going to say - DD has a huge bum and she was in them until about 18 months, and only stopped because she wanted pull ups. They aren't as absorbant as a tots, but still are pretty good.
I think it was the basic that I used, and a t-shirt would have been about as good... I'm assuming that the classic would be a few steps up from that though.
I don't know any cloth mums who choose kushies as their full time choice (the whole handful of cloth mums I know in rl ), but I do have a few of the basics for those times when they poo late in the day, but its that hour or so too early to put the night time one on, and they just about cope with that.
expat - I've been using kissaluvs on my dd who is 17 months now, she's still in size 1. They are a great slim fitting nappy , hope you like them when they arrive!
~(must order some larger ones soon.....!)
what's your cheap source then?
