Throwing temper coz yr kid cant express his feeling. u need to guide him to speak more or hv him to point at the feeling card if he cant speak. Start teaching him to express himself w simple words.
Also OT (i.e. Body brush) or going park to release his energy wud also help.
Also put him in a comfort zone whenhe threw the temper. Give him a clear signal that u wud ignore him w his bad temper and care him only when he calm down.
Doing the above wont work immediately but u will see improvements week by week.
