I find that it helps to step back and put things in priority and perspective, which always means my kids and my husband are at the top of the list. Then, whatever the day's trauma, it always seems less overwhelming!
And, (I put this in my 101 Tips in my book) can't we ALL take a second, close our eyes, and remember the sweet smell of our 'new baby?' THAT's why we do what we do, isn't it? And, THAT's all that really matters!
