Now we think our giant son may be teething already. For the two weeks or so after he got his shots, he kept running a low grade fever. I finally took him back to see Dr. Krumian , He checked him over and pronounced him fine and said to not bother with any more Tylenol. He said sometimes babies just don’t regulate their temperature very well at first. But considering the excessive drooling he is doing and the constant gnawing of fists or whatever else he can get in his mouth, early teething seems to be a likely culprit. Hopefully the actual teeth won’t appear too early. I don’t want any surprise chomping during meals.
