Ahi still does this from time to time. But she is playing and she bites down but not hard. If you know what I mean. Like she is holding my toe or my hand with her mouth.(There is no pressure just her mouth over me.) She used to bite harder but I just kept being consistent and told her a firm NO and replaced it with a chewy or toy. She caught on. I think she does it now to stop me from walking away from her.
