A pacifier can soothe a baby, but once it falls out of their mouth onto the floor it can give the tiniest person a tantrum.
That's why many parents clean them off with their mouth when there's no place to wash it off.
It turns out, that's ok.
Research says not only is good, old fashion spit-cleaning safe, it's beneficial for your child.
A study out of Sweden indicates when a mom sucks on a pacifier, it can actually strengthen a babies immune system and even keep certain allergies from developing.
