If your child only finishes 60 percent of what's on his plate for dinner, don't consider it a failure.

A Cornell University study says that unlike adults, who generally manage to eat almost every morsel of food in front of them, youngsters will only down around 60 percent of their meal on average.

They reached that conclusion after analyzing six studies of more than 320 children in elementary school.

The latest study found that kids' taste buds aren't as refined as adults, they're still trying to determine what they like to eat.

Most parents want their children to eat healthy, which includes portions of vegetables that kids normally turn their noses up at.   So yes, 60 percent is the norm.
