Bella is almost 9 months old and she is still chewing and grabbing us with her mouth. She doesn't really bite us, so to speak, but she wants to put her mouth on our hands and arms and chew. She has done it since she was 8 weeks old and I kept thinking she would out grow it. We don't allow her do it and tell her "NO!" when she does, but she still does it. She does it to me more than anyone and mostly when she is excited or when she hasn't seen me in a little while. It is really a little excessive with me, how can I get her to stop?
