How do I deal with my 2 year old's awful temper tantrums? They can last 40+ minutes. He has just spent 40 minutes smashing up the house and throwing toys at me and screaming because I told him to stop throwing Lego down the stairs. I try getting down to his level and speaking calmly, telling him off but not yelling, time out (he won't stay in the place I put him in, doesn't understand the concept tbh), reasoning with him and sometimes shouting when I can't take anymore (awful I know). He doesn't give a shit, just carries on with whatever it was I asked him not to do.
