Hi Daisy
My little one had nappy rash pretty much from birth- my HV (wrongly) decided it was thrush and doctor prescribed a very strong cream (timodine) with steroids in it which made little ones bum worse.
I tried metanium and bepanthen- neither worked for weeks.
It was a very stressful time, in the end we just did a ridiculous amount of non nappy time,, as much as practical- its hard, but worth it. Baby even went to sleep on change mat with a terry towel pegged around him.
i remember ringing the HV after two doctors visits andher saying shes never known nappy rash to last forever, I didnt believe her. The doc said I probably just had one of those babies- she was right!
The nappy rash eventually cleared- about seven weeks I think. I have been using Bepanthen religiously and it does the job for us, metanium didnt really help- but I hear it is different things for different babies.
Now it comes and goes and he does get a very red bum on occasions (then I leave his nappy off for a bit during changes (5-10 mins; not the hours I did initially) I just keep up with my regime and it goes quickly too. Nowadays his bum is good more often than bad- though there's often some hints of red. It does seem to go in a cycle, but now I know it will go and it is manageable it is far less stressful and as they start poohing less it does get better.
Now I whip his nappy off as soon as he poohs, use a cotton wool pad with water (never wipes, not even water wipes- they have chemicals in too) dry bum with terry towel, thin layer of bepanthen after airing bum for a few minutes every now and then.
He's 5 months now and the doc was right- he's just one of those babies.
