Why is my baby not urinating?

I am concerned that my five-month old baby may not be urinating. It seems like her diapers aren't as wet as they should be.  

She is eating (sucking) well.   Should I be concerned?

Changes in urinary patterns can occur for a variety of reasons, but the primary concern is that her decrease in urination could be a sign of dehydration.  

When babies are ill, they will typically take less volume of fluids, but we would still want to make sure that they urinate every 6-8 hours.  If babies are not urinating at least 3-4 times in 24 hours, that can be a sign of dehydration.

It would be important to contact her physician to discuss what her current urinary frequency is, what her feeding patterns are, if she is having any symptoms of vomiting or diarrhea and to determine if she needs to be seen for her decreased urination.
