I like the Oh-oh song from Love and Logic ( loveandlogic.com ) That site will tell more on how and when to start timeouts and discipline, but you sing ♪ OH-Oh, ♪ Need a little bedroom time ♪ You can come when your sweet ♪, You put her in her room, and give the option of the door being open or closed, if she throws a toy or try's to get out, it means she wants it closed, then you set the timer starting when she is calm. Now thats the Love and logic approach, but she'll learn, when you Sing ♪ Oh-Ohhh ♪ , Over time, she'll know what that means. Not much more needs to be said.
