DS has been coming up with a rash around his legs recently mainly after wearing a bbh night nappy with a BBH PUL cover. It looks really ouchie and seems to be from where the leg holes of the cover meet his legs iykwim. He also has been getting a bit of a rash over his bum after using the nappy overnight and when you open it in the morning it is really wet and the smell of ammonia is huge. I have a feeling that the issue is due to the cover as last night he went to bed with his usual bbh multi fit with extra boosting and his legs and bum looked marginally better in the morning. Anyone have any insight into what is going on? Should we try another cover and if so what would be good? I really want to continue using the night nappy as it is one of the only nappies that can contain his huge night time wee's..
