Dear L., My son got an UTI at that age once after he was antibiotics. At that age they do tend to want to play more and if the hold it sometimes bacteria can form. There is a bug going around with a low temp and tummy ache. It is really easy for the doc to do a urine test He probably will think it is cool to pee in a cup. When moms have a hunch it is usually right. Take him in for your peace of mind.. Hope he feels better, M.
