My 2year old has a bad case of diarrhoea which started yesterday morning. She is taking in fluids so I'm not worried about dehydration but I'm mainly concerned with her sore bum. I've been using wet wipes to clean her after a dirty nappy but her bumhole (sorry couldn't think of a better word) and the immediate surrounding area has become red and sore. There are slight purpley bits too which I'm assuming are the beginnings of piles as she's been going so frequently. Since the soreness I have been using sudocrem after a change and aqueous cream during so that any bits come off with less wiping iyswim. She has been yelping, squirming, jumping and now sobbing in pain at every change. I've swapped to warm water and cotton wool with sudocrem after but she's still finding the changes painful, bless her. Any suggestions?
