No, she definitely doesn't have reflux.
And she does seem aware of her surroundings. It's like, we're playing, and she'll shake her head, and I always stop and stare at her, cause it freaks me out, and she'll look at me and smile, and do it again. So it doesn't seem pathological, but it worries me. At first I thought it was the wobbly baby getting her balance thing, but she's beyond that phase now.
