Discovery of the Pacifier

So, Brady hasn't been a pacifier user for quite awhile. Sometime around month 3, he discovered his index finger was much more readily available, so he's been sucking on his fingers rather than his pacifier for a few months now. However, he has recently re-discovered his pacifier. But only for chewing purposes. I don't know if it makes his teeth feel better or what it does, but he plays with it like any other toy.
