Finally got my IRN to lay on her back in the palm of my hand. Bean working on doing it for a little while, basically just twirling her upside down on my finger and letting her rest in my palm while still holding on. Been working up to getting her to gently let go after laying there, and finally got her to stay long enough to get a picture.
... she's still a bitey little brat who thinks screeching at me and biting are just as fun as the actual training goes, but at least we're both having fun. She's always quiet and content after our sessions.
