2 year old son with bad behaviour

Hi there

I am hoping in getting some help for my son who has turned two. He is driving all of us crazy. He has been miss behaving for a while now.
He won't listen to anything I say, his constantly running and falling and hurting himself. He doesn't eat well, his just always up to mischief. I try to be assertive and strict and he still doesn't take me seriously. When he doesn't get his way he screams, cries and hits me. His always telling me to go in the naughty corner. His strong willed but also cries easily and sensitive nature. Not good in crowds but behaves well around strangers but naughty with ppl he knows. He goes to child care three times a week and is stubborn there too

I really would like for him to calm down. He easily gets distracted, always ask for lollies even though I never give it to him....just always testing me. His afraid of loud noise like motorcycle and lawn mower. He hates getting change - nappy change or clothes change. Basically everyday without a miss he will cry to get changed.

I'm really worried his going to hurt himself. He runs away from me when his let out of the pram or in the front of my house. His also managed to lose a tooth already from falling.

He always wants his dummy and if I don't give it to him he carries on. If he doesnt have the dummy he has been putting his finger in his mouth. His second molar teeth still haven't come through yet.

Pls someone if anyone can help us

Thanks in advance
