What could be wrong with my 6 month old. she's not wanting to eat?

Your six : Month old baby is not feeling good.She is trying to tell you something. Please take her to the doctor first thing in the morning if she is still not eating, running a fever, decrease voids , fussy or having problems with breathing.In the meantime , offer her the bottle as often as you can .Keeping down half an ounce every half hour is better than nothing.Tylenol (acetaminophen) if with fever.Make her comfortable.
