Standing up, spitting up, rolling over

Here's Elsie doing one of her favorite things lately - standing up. Of course, she also tends to spit up a bit, which she did just before I took this picture - on her papa. And the other morning she rolled over as if she'd been doing it for weeks - from front to back. I thought maybe it was a fluke so I put her back and watched. She did it again. And again. She's a pro now. She only goes in one direction.
