Teething?

Sa

FTM so no clue about what to expect... my little man has been very fussy for the past few days. He usually sleeps pretty well, but doesn’t seem to fall asleep very easily anymore. His hands are always in his mouth (I have to pull them away just to get a bottle in him). He wears a bib all day simply to catch all the drool. To me it seems like he is teething? Weird part is... he is only 2 months old! Is it possible for one so young to already show signs of teething? On a side note: apparently I had 4 teeth by 4 months according to my mom
