Yesterday DS developed shocking nappy rash in the space of about 1 hour. She's 16 weeks and normally doesn't get nappy rash, possibly because I use cloth nappies and give her time with her nappy off every day. Only change I can think of is that recently we switched to Pampers for her night-time disposable - this used to give her a slight rash as a newborn but I though she might have grown out of it. I'm going to put a fleece liner in the Pampers to provide a shield for her bottom until they're used up. Does anyone have any other ideas?? Thanks
