I have been told (and not had the chance to use this tip yet, but it was a very reliable source who has three lovely kids) that the best ever nappy rash stuff is baking soda and water made into a paste and put on the skin (it makes sense as it neutralises the acidic urine or poop which causes nappy rash). Nappy free time is also a GREAT cure and don't use wipes but use cotton wool soaked in warm water only (no soaps!). Also hydrozole cream avail OTC at chemists is great on fungal rashes/allergy rashes..... HTH!!!!
