Misbehaviour

Hi everyone, I'm still struggling with how to handle my daughter's misbehaviour. She is 3.5 yo now. SinceC she turned 3 years old, she is often to hit things or people when she gets angry. We tried many ways and she finally can control the hitting (she can stop mid air and not hitting in the end) and less hitting now🥹

Nowadays, she starts stomping her foot and screaming and growling whe she is angry. She hasnt started school yet and me and mu husband want to fix it before her class this july.

We tried punisment like time out, talking to her before napping and sleepinng at night, talking to her before going to public spaces, and signing her up with some classes that has lots of kids. We think that she needs to get used to have lots of kids and learn how to socialize more.

She also likes to scream at kids saying dont do that, dont do this, and she also likes to yell at kids at public places when the kids accidentally looking at her or pointing at her or things.

Maybe some of you are able to kindly share tips pr experiences, it will helps a lot. Thank you so much guys
