I see this thread was about a month ago. I was wondering what your progress/outcome was. My (nearly) 12 month old started biting at about 9 months and hasn't really stopped. Im sensing as the months go by that it might be a way for him to communicate with me, as he does it mainly as he is approaching his nap times. Not always - but mainly. I talked with my health nurse about it as I also wanted to nip this in the bud early, but no amount of 'No's" have made a difference. He doesn't bite anyone else except me and my husband. He also tends to bite areas he doesn't see often, like my legs (if Im about to get in the bath or something). Anyway, the post was to see if anything had changed with yours and interested in any other comments.
