My friend's 3 year old daughter is plagued by recurrent UTI's. She is under the care of a Nephrologist and has had many tests and radiological procedures.

I was wondering if anyone has had a small child with a similar problem, and if so, were there any natural remedies that you found useful.

Has anybody tried giving cranberries or regular cranberry juice to a child for this reason and if so, did it help to prevent UTI's?
