Ryatha I have tried everything. It can't be food related or it wouldn't clear up when he is in disposables. I have tried strip washing, using liners, only using bamboo velour inners, washing without powder, washing with powder, using the drier, not using the drier. He's had the rash for over a month now, probably closer to 2 months. Both times I have changed him to disposables it has gone straight away.
He's always been sensitive to washing powders and synthetic inners, this is different. It is sores and some are open.
