i too would love to know!! i might try the 'no respose' and see if it helps. I have tied the biting back but I think he is too young to understand? it just hurts so much sometimes its hard not to react! sometimes i feel like DS hates me because he hurts me so much with biting and hiting! i am really struggling to keep my patience at this age!! (20mths) ohhh and he has biten me while BF and it looked as though my nipple was about to come off!! thank god he at least doesnt do that anymore! GOOD LUCK DACH
