Draka my little girl has allways been nipping at my fingers, she got me good a few times so i had the thought that she must be thinking that my figers where snacks, now to correct this mistake. (this would not be recomend for kids or the squemish)
The idea was to just let her go to town with one of my fingers so to speak and when she realized she could not eat it, then it would not be food. I gave it a try and it felt like a tinny pair of pliers pinching away, then she gave up, this took two turns and now she no longer nips at my fingers! lol she still gives them a good look though!
