Looks like a typical eczema or rash. You can moisturise generously with QV or Ceradan (doctor prescribed these 2 brands to my baby with eczema). There are mixed opinions on usage of steroid cream, but I personally feel short term usage is fine as long as you don't abuse it.
Maybe can try eczema cream Or moisturizer?
Thanks all. Will try and hope it subsides.
Apply moisturiser immediately after bath.
Ceredan cream
Tried creams?
Try Aveeno
