Dear Doctor, I am a father of a 5 month old infant. She has had a bad cold, and our pediatrician suggested giving her Sinarest AF syrup, 0.3 ml each time, twice a day for 3 days. Unfortunately, we read that as 0.8ml as it was handwritten and gave her that much in the morning. That is the only time we have given her that so far. Would it cause any problem to her and what is the best way out from here?
