Oni was *just* like that!! But the only thing, she acted like that towards me too!!!
She just wanted to *get down*!!!! So I put her down, and she would squiggle, and squirm everywhere!!
She was very very independent from a very young age!!!
She got suuuper pissed and still does if you try to hold her back like a baby!!!!! I'd have to wrestle with her to get her to let me snuggle like that!!

that started at like 4 months!!
So when she starts gettin antsy with the inlaws, try having them just put her down on the floor, or sit her up in her bumbo!! Then you can get down on the floor and play with her!!
