I don't see it as dominance at all. Affection. I've had cats that did that. Always had to have a paw on my hand. And cats aren't really known for having to dominate anyone, as far as a pack mentality. Baby will take her paw and grab my lower lip and pull it to her face when she wants a kiss but that's about as aggressive as she gets. And that doesn't bother me a bit...
Unless, of course her nails need trimming.
