Ds (nearly 21 weeks) has been having a bit of a low patch with teething symptoms but over the last 48hrs things have got really nasty in nappies. He's been getting about 8-12 dirty nappies a day, they smell of vinegar and they've burnt through his skin leaving him with raw flesh and red 'blisters' along the line of his bum. On Tuesday afternoon the HV told me this 'nappy rash' was quite a normal part of teething etc, but I find it difficult to believe. For a start it is less like a rash and more like a burn, the skin is really hot to touch and ds is screaming in agony anytime we go near his nappies or even if he poos with his nappy off. The poo is really yuck oily greenish liquid. I've got some bepanthen which I've been putting on but it doesn't seen to be working very effectively.
Has anybody else experienced this with their dcs? Is there anything I can do? (I really hate seeing ds in this much pain. He's only asleep now because he has cried so much today he couldn't stay awake any longer.) TIA
