I know this was a previous thread, but i am experiencing the same problems with Gracie. She will bite hands and arms it seems, but it doesn't seem aggressive, only playful. I read on a site to try crying really loud when they bite, and it works, she'll stop in her tracks and look at me like "i'm sorry!" but i feel ridiculous fake crying at the top of my lungs, i have neighbors! I'm really frustrated, i don't know how to teach her that this is unacceptable play! Gracie is about 7 months old, and has been doing this for a while, any suggestions??
