Should we drug our children?

An interesting topic that got us talking in our editorial meeting today; the National Health Service in the UK have released new guidelines for the treatment of Attention Deficit and Hyperactivity Disorder (ADHD). It advises doctors and parents to avoid the use of Ritalin (Methyphendiate) in all but the most extreme cases and stop its use altogether for those under the age of five.  Should it be up to the parents to decide whether or not their children take the drug?
