Mouthing when Mad - 9 months
Our female is 9 months old, and mouths when she gets mad. We have never allowed mouthing, and she knows it's wrong.
She receives extensive attention and has had a very privileged life.
She only mouths when she's mad (not when she's excited or anything). For example, tonight she tried to steal a piece of chicken off a plate, and when she was told no, she started.
I don't know if this is teen behavior, or if it's something I should be concerned about. Please help!
