My 5 week old developed 1 week ago. It’s progressively spread. I’ve spoken to three GPS all giving different diagnoses. Eczema, new born rash or a reaction. I’ve used the cream they’ve given me but things just don’t seem to be improving. I’m a new mum and just feeling a bit lost for what to do. Has anyone had their baby experience similar? I thought maybe it could be a CMPA allergy but the GPs shrugged that off
