Another First....Her First Tooth

So all day Sunday (January 20th), Avery was not in a good mood, just generally fussy and unhappy, which is not our "normal" girl.  She was also drooling everywhere. John and I assumed that she was teething, but we did not see any teeth peeking through her gums.  Then, it appeared on Monday morning.  I apologize for the picture, but it is quite difficult to get a 7 month old to hold her mouth open and her tongue out of the way for any duration of time.
