I've got bumgenius v3 nappies. I wash them with a very small amount of surcare and do an extra rinse. Whenever mu LO wears them within hours he has nappy rash and everywhere that the nappy was touching his bottom is red whenever we put him back in the dreaded disposables the nappy rash disappears and his bottom returns to being nice baby pink. Is it possible that he's allergic to the bumgenius nappies? Has anyone else had any experience of this? I'm absolutely gutted as I really don't want to use disposables but we've tried for a few weeks now on and off and I can't keep putting him through having a sore bum any advice welcome... Thanks
