Oscar (4 years old) has been in my home for exactly one month today. Just yesterday he started the arm waving thing at me. Most times a black beard goes along with it. While the arm waving is adorable, I'd like to know if there is anything I can do to make him feel more secure and comfortable? I don't know why this just started yesterday, but I want him to be happy here. He did this last evening and again this afternoon.
