7 month old baby boy with 100.4 degree fever. Has had some vomiting in past few days (not bad... but distinguishable from spitting up). Urine smells strong. He s been sleeping a lot more than normal today, and fussier than usual. It s late at night. Is this urgent (probably ER since Urgent Cares are closed already) or can it wait until morning to have a normal office visit?
