Hi S.,
Make sure there's nothing under the pad of her car seat...also, you can fold a blanket or put a piece of foam under there. There isn't much padding and she might just be miserably uncomfortable. Other than that, I'd just ignore it. Kids learn to manipulate very early. I liked the idea of stopping along the road until she calms down. Kids hate being restrained for long periods of time. If they know its taking longer, they usually chill.
