As of June 6th 2013, Health Canada released an update recommending that codeine not be used in children less than 12 years of age. It appears that the use of NSAIDs (Advil) and Acetaminophen (Tylenol) along with Morphine (in cases of severe pain) are the recommended routes to treat pain in pediatric cases.
