I read MTTTT early, and it helped so much. I have 2 kids - one 3 and the other almost 2 - with opposite personalities. Just after each turned 1, they realized how to throw a tantrum. Each time, I calmly sent them to their room "until you're done crying." The older one stopped (pretty much) by 2, and the younger one tells me "done crying" as soon as I tell him to go. My house is so much quieter than my poor neighbor who has kids the same age. Now, they aren't perfect, but they're pretty good. And my husband and I take full credit (sorry John!).
