A. had a pretty toothless grin until she was 9.5 months old. She would occasionally act like she was teething, but we never saw any teeth until last week when she got her first tooth. Now, as best I can tell, she's working on at least 3-4 more...she wants to be next to me constantly. Thank goodness for babywearing. We are dancing and baking and doing the dishes. While she's not happy, she's happier than she was.
