Parents might want to limit the use of pacifiers for baby boys because they could hamper their emotional development.

The University Of Wisconsin- Madison found baby boys who use pacifiers can't mimic facial expressions of other people. It says college-aged men who reported more pacifier use as kids scored lower on tests of perspective-taking, which is a component of empathy.

Researchers say girls didn't show the same effect, possibly because they might develop emotionally before or despite pacifier use.
