My baby just turned 2 months old, is it possible 4 her to be teething already?!!?

My baby has been drooling a little more then usual. putting her fist in her mouth.. trying to bite on pacifier. fussy.... feeling hot at times. My mom and grandma say they can feel a little bump on her bottom gum.they say she is teething by the way she has been acting. Me and her dad can not believe that a 2 month old could be teething... is it possible, well i know anything is possible.. but has this happen to any of your children?! please let me know what to do to make her feel better.. im a new mommy! lots of learning. thank you!
