Time to Enforce the No Biting Rule

Libby has just accomplished another milestone. She now has her first tooth through. We figured it was coming because she has been chewing like crazy, but it still surprised me last night when she bit down on my finger and I felt that the entire tooth was through. I imagine the next tooth is not far behind because she is still chomping away on all her toys. Also, it appears that Libby is days away from being able to sit up by herself. She is very close, but not quite there yet. They do grow up fast don't they?
