Hiya,
If the nappy rash is like little red spots or not starting to get better by tomorrow it's worth checking with your doctor or HV as it may be a thrush infection.
Wipes often irritate skin as they are usually wetted with alcohol which is drying. You can get wipes which aren't, such as Ellie Smellie or some organic ones which are nice. Often these are wetted with aloe vera. If possible, though, just use cotton wool and water, or consider using washable wipes and water which you can throw in the wash with your nappies. You can buy special wipes squares, or just cut up an old towel!
I would avoid creams unless baby is sore - you really don't need them all the time.
Personally, I think that using cloth nappies such as Tots Bots is better for the skin, and my favourite is bamboo, eg Tots Bots Bamboozles or Wham-Bamboos as they are naturally anti-bacterial and anti-fungal, so great for helping to stop nappy rash.
The very best thing is nappy off time, of course - so let your baby kick on a washable play mat or several folded towels for as long as possible during the day - this really makes a difference.
Just keep an eye on her now, though, as nappy rash can get worse very, very quickly.
