I got a new baby girl, and when I was buying her she was very well behaved, but after I got her home I realised she was a compulsive biter. My ear, cheek, lips, nose, fingers, anything she can get her beak around. And it's not light nibbling it's hard bites that hurt. Do they grow out of this behaviour, or is there anything I can do to train her not to do it? It's so nerve wracking having her on my shoulder.
