Harper is now working on sitting up and scooting. She's able to sit up unassisted for about a minute or so and she can sit in her highchair easily too. She can sit up on a lap for forever (in fact she's sitting on mine right now) and likes to read books that way. She is scooting on her back pretty well, and she pushes off my hands when she's on her tummy to project herself forward toward a toy. It's exciting to watch her become more mobile and independent, but also a bit scary knowing that soon I'll begin the chasing game and I'll have to actually babyproof. We're moving in a couple of weeks and if the move coincides with Harper's newfound mobility, it could be a recipe for a headache. We'll see!
