Dd (9 months) has a nappy rash which is not improving, in fact worsening with Sudocrem, which usually does the trick. Red with little spots that look like blisters or pimples from reading other threads it sounds like thrush so I was going to try Canesten on it. I've got both Canesten and Canesten HC from a fungal infection she had behind her ear a few months back which to use? Or hold off until she's seen the doctor?
