You're out with your baby and the pacifier falls on the ground. You pop it in your mouth to "clean" it and give it back to your baby. Can that simple act affect your baby's future allergies?

Americans are are no strangers to hay fever and other allergies. Yet Americans born outside of the US may have to deal with these conditions less than those born in the US.

Researchers already knew that milk allergy was common among American children. But until recently, they weren’t sure how it compared to other food allergies.
