Duke study reveals something about affectionate moms

That is the key finding of research from a 30-year study, headed by a Duke University Medical School professor.

The study looked at 500 children and found that those whose mothers hugged them and kissed them a lot, grew into adults who were less anxious and more confident.

Researchers say it boils down to mothers teaching babies how to regulate their emotions -- something they're not born knowing how to do.
