So you would think that if a baby's pacifier falls out you would clean it with water.  Well, a new study says, that parents who pick up the pacifier and LICK it and put it back in their baby's mouth is a good thing.

The study says that it actually helps the baby's immune system and is much better than rinsing it with water . So, next time the pacifier falls, pick it up, suck it then put it back in their mouth.

Just make sure it's your baby and not someone else  LOL.
