ladies with babies with teeth!

Ladies that have babies with teeth already..
How fussy was your LO before their teeth cut through?? My LO just turned 5 months and he's been especially fussy tonight.. he's been shoving almost his whole hand in his mouth. 
Tries to put my hand in his mouth..has been having trouble sleeping..lots of drool.. and has been whiney.. did your LO act normal? Or were they fussy before their tooth finally popped out?
