He probably is! The teething symptoms can start a long time before you see a tooth. My first had his two bottom teeth at 4 months, and really never exhibited much in the way of classic teething signs, but my 7 month old baby is a classic teether -drooling, gnawing, fussiness -the whole nine yards since he was about 3 months. He now has his two front bottom teeth, but they've taken a good 2 1/2 months to appear, push through and grow up in his mouth.
