DD is 12 weeks old and she has been drooling more and more in the past week or so and since the weekend she has been fussy (hardly ever cries normally) and chewing on whatever she can get....especially cloth. Could she be teething this soon? I think she might also be hitting her 3 month growth spurt. How long will the pain of cutting that first tooth last? I feel so bad for her, I know it's got to be so uncomfortable!
