Oh im not looking forward to those days. Jesse already sometime whines when he doesnt want to lay on the floor no more!
My sister uses threats too like do you want to play the xbox this afternoon, "yes" well stop otherwise you wont be. Thats to my 7 year old nephew. Prob different with a 3 year old but perhaps the going to the room thing or time out might be a good thing to introduce.
Best of luck
