Teething...or Toothing?

My baby has her first tooth!!! The other day Jordan said "I think I feel something poking up through her gums." I said that weeks ago, but whatever it was seemed to go away. Yesturday, I was rubbing her gums and felt something sharp! I looked in there and the littlest tooth was just starting to poke through the gum line! I can't believe she has a tooth already...she's not even 6 months! Hopefully this teething thing won't be as bad as everyone tells me it is!
