She's got a good head on her shoulders...

And she can basically hold it up on her own now, when she is being held upright in your arms at least. One of the ways we spend "wake time" is by having "tummy time", during which she gets thoroughly frustrated with herself because she can't crawl or push herself up like she wants. Originally we thought she was pretty calm, but she can kick up a storm and loves to squirm all over the place, even out of your arms, if she was strong enough!
