Happy Smile?

So lately Ella has been giving this really goofy grin. She started doing it a few weeks ago and would breath in and out of her nose really fast. We would all laugh and she would do it more and more, now the breathing sound is gone and she almost looks like she will start growling, lean over, and bite you. She looks so much like Lewis when she does it. I think its her eyes and her brow.

She is also starting to move a little more. No crawling yet, but she will lift her butt off the floor to lean over and get toys, sometimes she is able to pivot herself, but she doesn't have any real control over that maneuver yet. She usually just falls onto her belly and cries until someone moves her. She is perfectly capable of rolling over onto her back, but she rarely does. She actually will roll over onto her belly in search of a toy, before she'll roll to her back. Strange kid, I know.
