Thanks for replying.

LOL they can't tap her nose because she knows she's not allowed to do that and runs off in a scurry! Oh and they do yell at her when she does it, believe me, I heard my dad on the phone.

That's another thing, they buy her all kinds of toys and she doesn't want to play with them. (the toys) They collect dust or when Teeko goes over he finally plays with them.

They are just sitting there and then all of a sudden BAM she bites and runs away.

Thanks again for your replies and suggestions, I'll let my parents know what you guys said.
