Pacifiers are Dangerous

I put Dustin down for a nap as usual, and he started to fuss, which I didn't think anything of (becuase he almost always fusses himself to sleep), but then he started to really cry. I went in his room to see what was wrong and he had an entire NUK pacifier lodged in his mouth backwards (so the end of the nipple was the only thing sticking out of his mouth). Can you believe that. I though pacifiers were baby-proof, but I thought wrong. We still give him his pacifier, especially since he's teething, but we take it out of the crib as soon as he falls asleep.
