I feel like ever since I got Sixer all I say is "No Sixer", "Stop Sixer". I know he is excited to see me when I get home but I can't get him to stop biting me or the couch. He does not want to sleep through the night. He gets up between 2 and 4 am and does not want to go back to sleep. Maybe he will grow out of this. I hope so because I am not getting much sleep anymore. Does anyone have any thoughts or suggestions?
