New Milestones

Lauren has hit a few milestones over the last couple of weeks. At 4 1/2 months she's now steady enough to play in her activity center:
She can sit up on her own for about 30 seconds:

And she's great at getting up on her elbows during tummy time:

She has also started rolling over from front to back.

But my favorite thing lately is how much she loves watching Mason. She is entertained by him more than anything else. And no one can make her laugh like he can. I'm trying hard to get a video of the two of them together, and I will post one if I can ever get it in time.
