Emma just sat up and scooted!
I was in the room with her and she was on all fours, practicing her Down Dog and then left for a moment. When I came back, she was sitting up and closer to the box she's been "talking" to for the last 5 minutes!
Then, while I watched, she leaned over from her sitting position and pulled herself closer to the box. Scootching! The Down Dog position helped her to figure out how to sit back up from all fours. Awesome! All the while she's been saying da-da-da and blowing raspberries. Also a first. (She started saying da-da-da on Saturday.)
She just did it again!
You know what this means: it's time to set up some barriers to mobility. Isn't that obnoxious? Hooray! You've figured out how to roughly get from Point A to Point B! Now that you've learned how to move around, we have to contain you.
