Terrible twos happened overnight...

My little girl has always been active..constantly busy and into everything..but she listened. She just started not listening and throwing huge tantrums at everything. Her behavior changed overnight...wow. I wasn’t prepared. I’m still not!! How does a mama deal with this type of behavior without losing my cool?! And does the “terrible twos” happen so quick?!
