Children's cold medicines and deaths related to cold meds

I was watching an episode of America Now yesterday. I found it very fasinating. However, they were talking about children's cold medicines and being a mom this caught my attention. According to a recent study that was done, three children die a year from cough medicine. It is unclear if it is from overdosing, an allergic reaction to the medicine or what. It is recommended that we treat or child's colds the old fashioned way. This would be by giving them chicken noodle soup, water and letting them get lots of rest. This old fashioned and tested remedy has always worked for ages.
