Sucking your baby's pacifier might protect them from allergies, study says

(CNN)Your baby's pacifier falls on the floor. Before giving it back to your child, do you wash it in a sink or, perhaps reluctantly, clean it with your own saliva?

Don't feel too guilty if you chose the latter, because a new study suggests that a mother's spit -- and the bacteria in it -- may help prevent allergies in young children.
The research found lower levels of a troublesome, allergy-causing protein in babies whose mothers reported sucking on their infants' pacifiers, adding to a growing body of evidence that early exposure to microbes may prevent allergies in children.
