It finally happened!

Sierra slept through the whole, entire, night!!!

I put her to bed at 9:30pm (still on Arizona time, I guess) and she was still sleeping at 7:30 this morning when Jason went to get her! (We had to close the door to protect ourselves from marauding cats and were worried we wouldn't hear her when she woke up) Whoo-hoo!!! Let's hope for many more of those!
