Teething?

We experienced a very miserable three weeks recently. We aren't exactly sure if Hannah was sick or just teething. First, we called the doctor. They said to wait a few days. After five days, we took her in. She was fine. After another week in .... we took her to the doctor again thinking it had surely developed into an ear ache. Nope! Nothing! One day, she was happy again. She mastered crawling shortly after. Now, she's usually pretty pleasant, as long as she gets her nap, oh and whatever else she wants from mom.
