Calming a hot temper

Q: My son is a lively 4-and-a-half year old but he battles with his temper. He gets annoyed and irritated so much and when one doesn’t do what he wants he just flares up and sometimes really loses the plot. 

He can be very aggressive at times and very argumentative which also sets him off.  I know these moments happen when he is tired after a long day, unfortunately it is affecting his relationship with his friends. What can I used to help calm his emotions?  He isnt always like this but mostly starts with friends around and when tired.  

A: Nux Vom  200c  4 – 6 times a day should do the trick!
