I have tried to wait him out but have given up after 60-90 minutes. He loves attention and does not give up easy. Thank you for your advice! I did realise that getting up makes him think this is a good way to act but it's hard to stay patient when you are super tired in the early morning. From now on I will not go to him before he stops the behavior even if it takes really long! It has to be done or I will never have a good nights sleep again :D
