My 9m/o has had the most excruciating nappy rash for the last two weeks. It just appeared overnight, she’d never had it before. It’s bright red with sore patches that don’t seem to heal. Not sure if it’s a coincidence or related but she also has a bad tummy lately, v frequent poos. I saw a GP who wasn’t very interested but prescribed us some steroid/antifungal cream... also been using that yellow cream everyone recommends, Wileda nappy cream, sudocrem, the lot! Plenty of bare-bum time but he bad tummy means this is perilous! My previously happy, chilled baby is now permanently moaning, no doubt in pain. Does this sound like normal nappy rash or something worse?
