I have a friend that used cloth from birth and she said that the meconium was no different to regular newborn runny poo as far as washing/staining was concerned. My sister used cloth from a couple of days old (she too was concerned about meconium) and although her fleece liners are a little stained her nappies themselves are fine. I'm not convinced the staining on her liners wasn't due her love of copious amounts of Bee Balm
If I had another baby I'd use cloth from birth
