First swing ride, first time down the slide and WHAT!??? is that a tooth?

We took Reese to the park today. Unfortunately I forgot the camera, but as I was pushing her on the swing and she was flashing me her pearly, ok well more like drooly gums, I noticed a little something in her mouth. I stopped to get a better look and sure enough, Reese's first tooth has broken through. I can't believe it! That probably explains why she's been a little whinny and clingy today. My baby is getting teeth!
