Jude has started biting me



He self weaned from his dummy at about 9 months, and he doesn't really need/like a comforter...just likes a cuddle! He does have his ratty for bed which he likes to drape the legs over his eyes to sleep and suck but doesn't miss it if it's not around iykwim. But lately i have noticed he will suck my top and then out of nowhere clamps down!! It's only me that he bites too so I presume it is a comfort thing or does my son just hate me. I've tried to say no firmly and move his head away but he just laughs at me.

Any ideas or do I just put up with it?? He drew blood yesterday so I'd like to nip this quick if I can
