UTI's

The thing that you want to watch all around is the risk of pylo.  That is especially true more in pregnant women.  Women, because of their anatomy are more prone to UTI's.  The elderly are prone due to the incontinence that some of them may have or the lack of fluids.  I would say that would be the problem with the children was the lack of fluids and not so much infection per say.  I would just make sure that they are wiping front to back and that they are drinking enough fluids and that they clean up after having sexual relations.  That tends to give a woman, pregnant or not , a UTI really quickly.
