How do you handle a kid who is violent in nature? That is scratched and beat you suddenly. Have held her hands and talk to her many x but nothing seems to work

A 2 yo child who is that angry, might be trying to attract your attention to her needs rather than her behaviour. Look beyond her behaviour. Look for the root cause for that anger, could it be you are not listening or talking to her? For my children, I will sternly take away their fav things eg their toys. Whenever they misbehave, I will tell them sternly that it is not acceptable and remove her toys. If they screamed, shout or scratched, hold them firmly and look into their eyes and hug them. Then in a gentle voice, tell them that it is a no no to hurt people and remove their toys. Set up a reward system by rewarding them with something good daily. Catch your child doing something good and affirm. Every child loves affirmation. When everything fails, just hold your child and hug. Tell your child that mummy is here.
