My DS 2 has super sensitive skin and as a 2 day old his butt was covered in red welts and bleeding

I was advised by the midwives to stop using commercial wipes, or if I had to then get the sensitive or fragrance free ones. That helped a bit to take the angryness out of the rash within a day or two.

We had to experiment with the cream a bit too and after a bit or trial and error it was curash or bepanthen that was the best for him. Looking back I also think he was sensitive to disposable nappies and is one reason why I use cloth for my youngest two. I couldn't leave his bum cream free after any nappy change otherwise it would be red and nasty for the next one and I'd change him 2 hourly unless he was sleeping. Once he was toilet trained his rash cleared up.
