My 5 year old DS was supposed to be having a big Xmas party on Saturday with some of his classmates at our house. His behavior has been terrible the last few weeks. I said to him last week if you don't improve im going to cancel your party. His reply was "see if i care " . Now i don't want to let down his friends who are all looking forward to the party. But i cant really let it go as an empty threat as he wont have learned anything.
