Sucking on your baby's pacifier may not seem like a big deal, but it actually could help prevent future allergies in your kids.

According to CBS News, new research published in the May 6 edition of Pediatrics suggests doing so can actually make them less likely to develop asthma, eczema and food allergies when compared to kids whose parents did not suck on their pacifiers.

Researchers studied 184 Swedish infants not born prematurely, with 80 percent having at least one parent with allergies.

They were tested for food and airborne allergies at 18 months and 3 years old. As they grew up, parents wrote down all the details of the first year of their lives, including illnesses and medications they took.

All parents were asked if the babies used pacifiers when they were six months old. They also asked how the pacifier was cleaned, by boiling, rinsing with water or by the parents sucking on it.

About 75 percent of the babies used pacifiers during the first six months of their lives. Most parents said they rinsed the pacifier in tap water, but half of them boiled it and 65 used their mouths to clean it.

The study showed kids whose parents sucked on pacifiers were 88 percent less likely to have asthma, 63 percent less likely to have eczema and were also less likely to have food allergies.
