Hi Doc My girl is 3-months new. She has been quite cranky for quite a few days; has been drooling, and has been taking her hand to her mouth too often. She even seems to moving her mouth as if chewing. Should we consider these as early symptoms of teething? Do infants start teething as early as 3 months? Is this normal? If yes, any tips on to soothe her pain? Please suggest. Thanks in advance. #asktheexpert
