Hi, just back from holiday in Spain and DD still has a very bad nappy rash (she is 15 months). Been giving lots of nappy off time but she is also cutting molars on the bottom. Sudocrem & Bepanthan not working that well. Just wondering if there is anything doctor could give on prescription to clear it up any quicker? Or any other ideas? It has been red and sore for almost 2 weeks now.
