I finally sat up all by myself. Not nuzzled in the corner of a couch, not leaning against a pillow, not propped up by my hands-all by myself. But then I went to get a closer look at mommy's computer and fell face first hitting my cheek on the computer and getting stuck in the crack on the couch.
Then at night, I rolled myself all the way over to my tummy, but didn't really want to stay that way and I couldn't roll back. Geez, so many problems being a big kid!
