Dd is 10mths and had very little nappy rash. Had a few spots that have been stubborn over the last week. Have been using sudocream and it seemed to be going but suddenly back with avengence. Two spots have broken the skin and are sore. It's the first time this has happened. Using metonium now. Should I continue with this or take her to the gp? Just worried about it getting worse. Ftm!!!!
