Some providers do not like certain things for a variety of reasons. I wouldn't overthink it too much, she may just not like having fingers used on her because due to nails they can harbor bacteria. In my experience my best sessions have been when I take a nice/friendly/reciprocal approach to activities. And if I want to try something that's very different than what's going on at the time, I would say "Is it ok if I XYZ?" and most times they say OK. Or not. It's happened. But I always think if you respect what they want, which is a way of making them happy, it pays off for you as well. Glad you had fun overall. How did you like Coco's enhancement? I was relieved she didn't go crazy big, and the Docter did a good job I thought..
