When your significant other snores, he or she may be banished to the spare bedroom. But what happens when it's your toddler making all that noise? Is it more than just an annoyance?

In a first of its kind study, researchers in Cincinnati, surveyed two-hundred-49 mothers about their kids' sleep, snoring and behavior. The mothers filled out questionnaires from the time of their baby's birth through a 3 year follow-up point.

22 of the children were reported to have persistent, loud snoring at least twice a week, at ages 2 and 3. This group had significantly worse overall behavior including hyperactivity, inattention and depression. Interestingly, children who were breastfed seemed to be protected against later snoring. And the longer they nursed, the better.

While most kids will snore occasionally, persistent snoring should be reported to your family's doctor.
