She may be exploring, or she may feel scared and be looking for a place to hide. I'd try sitting with a blanket, and make a little cave for her to go into. See if she likes that. or if you have a hoodie that has the pocket for your hands on the front, put her in there... Give her a place to hide while you're sitting with her see if that makes a difference. Sometimes that works for me, other times, mine just wants to move... I keep an eye on her, and never let her get out of reach, but will let her roam to see where she goes.
I look at it like a toddler... if you hold them back, they just want to go more... if you let them explore, it becomes not as interesting and they become happy to stay where they're at. LOL..
