My baby girl is 17 months old she has a runny nose, slight cough and a low grade temp. She slept all night I went to get her up this morning and her temp. was 102 she was a little shaky. Administered Tylenol, put her in the bath to cool her down, and also applied a washcloth to her forehead. Within 1 hour it was down to 100 degrees. When should I be concerened to take her into the doctor or how high of a temp. Her brother had these same symptoms and is just starting to get over his cold.
