Losing it

Sometimes William (and occasionally Wynn) can really push my buttons. It's usually when I'm already tired, at the end of a long day that started too early. He will be tired too and will not listen. But, he will do something, almost anything, that makes me angry. Instead of being a calm parent, I raise my voice and stomp around.
I've read enough parenting books to know that losing my temper is the worst way to parent. That it is through calmness they learn to make better decisions on their own.
So, I am gong to try to count to 10 before I react. Maybe I'll keep a journal of things that really get me going, so that I can find ways to avoid certain situations.
I want to be a good mom and as calm as possible.
