benadryl

My little one had to go to the hospital for a really bad cold that I thought might turn into bronchitis so just to make sure. She has had a low-grade fever. Anyways she has a ear infection and a cold of course, the doctor there said I can give her benadryl but 4cc.. Which is 4ml.. Is that too much!? I haven't gave her any because Im scared that 4cc is way to much she's only 11 months old.
