my baby is 6.5 months old and has cold, he is unable to open eyes in the morning because of mucus, mucus comes in eyes even when he takes short naps in daytime. Also there is mild fever in the morning, Its been 5 days now, Doctor advised to give Wikoryl drops 3 times a day, given these drops yesterday and today twice but its not showing any positive result. Should I wait or need to give some other medicine
