I've always used Sudocrem, but only when needed (i.e. only when redness/rash was getting out of hand). And that's only with a liner. I found using a liner on it's own was often enough to deal with nappy rash - it helped keep moisture away, which gave DD's bum a chance to stay dry for a bit to deal with the redness/rash before the next poo came along...

What also helped us, as Gigi says, was that I only ever used cotton wool and water to clean her and then a soft cloth to dry her, and we also use a non-biological washing detergent in our house (i.e. much gentler on both baby and the nappies without the enzymes - not sure what they are referred to Australia as I never had to worry about it before we moved over here!) Doing all that meant that we rarely needed any nappy/barrier cream at all!
