Diana discovered the reason for Simon's general crankiness and mouth pain. Sure, we were looking at the tiny lump and white spot on his lower right gum, but this morning she found not one, but two teeth coming in on his upper left! We weren't even looking there! So that means he's been cutting at least three teeth in the last week, and that's why he's been so miserable. I say at least, because it appears that a fourth might be trying to breach on the lower left as well.
This evening, he has been extending out his lower jaw and making strange faces, probing his mouth with his tongue. I think he's as surprised as we are, because he's not sure what to make of these things in his mouth. The faces are absolutely hilarious, and we'll have to get some photos.
As much as I hate to see him all miserable like this, it might be a relief if he does a lot of teeth quickly. I don't think any of his PEPS buddies have any yet. I've heard horror stories of continuous, one at a time teething that took forever, so perhaps this is a good thing.
Happy Simon was back this evening. :)
