Stomatitis????

I've never even heard of stomatitis!!  Paxton wasn't acting like himself for the past couple of days.  Not eating well, waking up at night and drooling.  I thought he was getting his 2 year molars.  Picked him up from school today and his poor tongue looked like this and his teacher said he cried for me all afternoon. :(.  Took him to the urgent care because I had no idea what it was (and feared hand, foot and mouth...again!).  Turns out it is called stomatitis. It took about 4 or 5 days to go away.  Once we started the miracle mouthwash he seemed to feel a little better.  Poor dude!
