Motherhood really does change everything, you know. A year ago I wouldn't have been up half the night and still eager to see the sun come up or hear that little giggle from the nursery. Even two months ago, I don't think that I'd be this happy to be awake now after waking up every two and a half hours all night long.

It's that little giggle that makes all the difference. When I go in to see her in the morning, and she's so happy to see me. Always happy to see me, so full of joy. Better than anything else I could imagine. As good as seeing my husband again after several weeks or months apart, and burrowing my face in his shoulder as his arms wrap around me.

With this in my life, who has time to be depressed?
