Atreyu has a little, ok big habit of suckling me. He goes for my neck, my lips, my eyes, my chest... anything he can get his little mouth to. He has a habit of sucking on my shirts too. To the point that my shirt is soaking wet. He has even crawled down my shirt and done this to my stomach - where he then proceeded to fall asleep which was really cute. I am thinking he was taken from his mom too soon - he was 6 weeks old when I got him. Is this something I should break him of?? I took it as a sign that he is hungry and have bought some kitten formula that I give him when he is doing this but I don't want to encourage this if its gonna be a problem for him for the rest of his 9 lives. I have never had a kitten before, always got them when they were at least a few months old. He always purrs when he does this so I know it makes him happy and it doesn't really bother me. I just worry
