Okay here's the thing, my 2 year old daughter is very very smart for her age, she just turned 2 in august, but she is soo bad and i exaggerate the word bad. She can be very moody but can change from cryin to laughin in .5 seconds, she is constantly moving, and i mean constantly, as in never sitting still except to use the bathroom, and to go to sleep, when she gets mad or upset, she throws things, she smacks things, knocks thing off the table, smacks herself and now she bites on her arm, I dont know what to do anymore because discipline doesnt seem to be the answer anymore please help
