DS1 (4.9) has his second urine infection in a few months. I think we will be referred for further investigation, as apparently it's relatively unusual in a boy his age. He's had a kidney/bladder ultrasound already which didn't flag up anything.
Anyone with experience of what sort of things might cause urine infections? He has coeliac disease, but there doesn't seem to be any link there. He also gets tonsillitis quite a lot, if that has any relevance.
