Was on here a few days back but had such an awful 3 days, had to ask you all for help again. DS is 16mo and has the itchiest, reddest bum round his willy. He has always suffered periodically but at the moment it's terrible. He woke at 9pm and 4am having scratched so hard that his nappy was in tatters. We've had 2 days of nappy off time but still no change. Is there ANYTHING you've tried or heard of that might ease his discomfort? Thanks so much.
