I sent my 3 year old to his room if he throws a tantrum, I personally dont belive he can throw a tantrum and have me have to stand/sit there and watch it.. and well he does less and less every day.. i think i get 1 a day if that.

He has no toys in his room.

If not laundry? bathroom.. send him there for 3 min.. for not respecting and listening to you and carrying on like a pork chop.

Good luck
