evgreen - I've been using charlie banana diapers for a week now for my newborn. I bought 'one size' and they are pretty big on a 4kg baby, but both the waist and legs are adjustable. They seem to be fine - no major leakages so far (though a newborn doesn't produce that much!) and I'm happy with them. I chose them for the price (around $750 for about 6 diapers and inserts) plus they have a disposable system option (disposable inserts instead of cloth inserts) and they say to wash them in cold water or water less than 40 C. We only have cold water at home and some cloth diaper brands recommend warm to hot water. I figured out that we'd pay for them in around 2-3 months by using them in place of disposables.
Ozmerc, it's encouraging to hear that you're happy with the CB diapers. I also bought the one-size diapers. Are you using cloth diapers exclusively? How many CB diapers do you go through a day for a newborn?
As I've said, I've not yet had a chance to try mine out yet because the baby has yet to arrive. However, I've already run them through the cold water wash and have found that the diaper shells dry very quickly on the washing line. The liners take a little longer to dry. Do you use a dryer or line dry?
