About a week ago I had a dream that I was telling someone that Harper had eight teeth (as she's had for a couple of months now) and as I was saying it, I looked in her mouth and counted sixteen. In the dream, I was like, "Woah! These showed up when I wasn't looking!"
Well, call it mother's intuition or whatever but it turns out, Harper does have a new tooth that poked through when I wasn't looking. Yesterday I was playing with her and held her upside down, and spotted a white spot on her right top gums. Upon closer examination, it was indeed a molar! It's been there for at least a week or two because it is already quite visible (when you go looking for it). I felt around on the other side and I can feel that the corresponding tooth is right below the surface of her gums but it is not poking through yet.
I just went online to check for typical molar tooth eruption in babies: the range is 12-16 months. At 10 1/2, Harper is super early. This explains the low grade fever she's had for a while now, the drool stool, and (hopefully) the night wakings. There's always something we can blame her wakefulness on.
