My 21 month old, 22 pound daughter has an ear infection and is being treated with amoxicillin plus tylenol for fever. Her most recent doses of the tylenol were at 7 AM, noon, and at 6 PM. I accidentally gave her another dose at 7 PM, just one hour after the previous dose. Each dose was 1.2 mL of the concentrated drops (120 mg, I believe.) Is there anything I should do or watch out for regarding potential overdose?
