My 6 month old has had Diarrhoea for 6 days and Nappy Rash that is now weeping. He is in alot of pain. Been give hydrocortisone by out of hours surgery to clear up but this hurts him and he cries when I put this on. Also tried sudocrem, bepanthen and zinc and castor oil. Any other quick fixes you can think of for his nappy area and the diarrhoea? Please help his in alot of pain and can't sit down.
