My LO is 15 months and for months and months when we take off his nappy he scratches his bum. There was never any rash so assumed it was the novelty of being able to reach that area . He would really scratch it in the bath particularly Fast forward to a couple of months ago and noticed he has quite dry skin. Then he starts scratching his tummy. Then his back.....then his legs. The skin again has no rash until he starts scratching and then it gets red and sometimes even bleeds from the scratching. After trying shea butter and some natural things for dry skin he was getting more annd more obviously bothered by it so i took him to dr yesterday who diagnosed contact dermititis and gave him hydrocortisone cream, piriton and an emolient moisturiser the question though is what could be causing it? As first it was only on his bum which wasnt coming into contact with laundry detergent, but if it was any other product it would surely have been all over from the start? And if it was from the nappy it wouldnt have spread elsewhere? I'm a bit flummoxed what can be causing it. Any ideas? He is sooo itchy! dont know if its relevant but he has actually never had a 'normal' nappy rash or any rash that hasnt been caused by his own scratching, so i didnt think he really had sensitive skin?
