Our sweet, cheerful little dude has been a total crankpot this week. Fussy, whiney, clingy, crying. Hands and everything else he can get into stuffed in his little mouth, chomping. His gums looks white and I see a white spot on the upper front tooth area. However, there is also a white spot on FRONT of the gum. Is this normal? Does this sound like teething? I thought this would be a long ways off
