Think we have found out part of the problem. My husband talked to the man we bought him from today and apparently he has had this issue for a long time. He worked with him and thought he had broken him from it but since he has been with us he has picked it back up. At least we now know that it's not completely something that we've done to make him start doing it. We just have to break him from doing it ourselves. Thanks for all the tips. We will take and use all of the suggestions.
