Hi. Good evening , my 8 months old boy, he had runny poo for 5 day now, before. I just use some sudocrem each time for nappy change, but yesterday I found he had a red and painful bottom, today seems not getting better, he must feel pain, and today he poo for 6 time, each time just a small runny water, what can I do now.do I need to take him to 24hours Gp ?
