When it comes to colds, flu and ear infections many theories exist on the best ways to treat these common ailments, however not all are true.

Eleven-year-old Ciara Richard says for quite a few years she believed a myth about how people got colds. "You get a cold by being cold. But that's not true."

Pediatrician Emilio Del Valle says that just like children, sometimes parents may tend to believe myths about common ailments like how to treat a cold. That old saying "feed a cold starve a fever?" Simply is a myth. "If you don't keep up with your nourishment when you have a cold, or any type of disease, your energy's run down and you feel worse."

Do you know if it's true that colds cause ear infections? Dr. Del Valle explains, "A cold itself is not going to be 100% of the time causing an ear infection but you're more prone to get an ear infection when you have a cold."

Another myth: the B.R.A.T. diet, which is an acronym for bananas, rice, applesauce and toast, is best for treating diarrhea. But in actuality it's best for something else. "The B.R.A.T. diet was designed most of the times initially for vomiting."

So, the B.R.A.T. diet may be popular but The American Academy of Pediatrics states that most children should continue to eat a normal diet including formula or milk while they have mild diarrhea.

Also, doctors tell John that yogurt with active cultures, may also be helpful when your child has diarrhea.
