yeast is an "opportunistic" fungal infection. yeast loves warm dark moist areas typical of a two-year old's diaper. yeast is airborne can colonize in the colon and can just happen to anyone if the right conditions exist. especially children with weaker less-challenged immune systems. children who recently used antibiotics for any reason are more likely to get diaper-area yeast infections. a urinary tract infection is very common in little girls especially those that are diapered. utis can be misdiagnosed if the urine specimen is not taken by a catheter and properly cultured in the lab. the most common pathogen causing a uti would be the various germs (enteric bacteria) present in stool that conveniently migrates into their tiny urethra. a urinary tract infection in little boys is uncommon and needs a higher level of diagnostic investigation.
