Recurrent UTI's in young children can be caused by Reflux Kidney Disease.The child's GP should refer them to a paediatric urology clinic for investigations.
Hi Ummmm, I guess you've had the answers you're looking for but I am now 45 and when I was three I was having many many urine infections., just to answer your actual question.
I used to get delirious and be semi comatose and over the first few years of my life I spent probably a third of each year in and out of hospital. Insist your child see's a Urologist as soon as possible.
