My Son is 14 months old and had a UTI when he was approx 8 months old, it took a stay in hospital and an IV line of anti-biotics to clear up this problem. A few days after this we noticed blood in his stools which was bright red at the start but now it is predominately black. For about the last two months we have noticed that his nappies are full of urine which has a very strong smell in the mornings especially. He has been brought back to see his GP on a number of occasions and has his urine tested, sometimes there is growth in the urine but they cannot determine what it is. He was last tested a week ago and he has a UTI again. He has been for a Renal Nuclear Scan two weeks ago and we are awaiting the results, we have taken him off dairy products as we suspect there is something in the proteins that are causing his problem, now he has no access to the Calcium and Vitamins he would get from Dairy products and has to see a Dietitian in the coming weeks.
