Whenever ds wants to show love he goes in with a big grin and then opens his mouth wide and tries to bite. It genuinely comes out of a loving impulse. I know I should remove him and say 'No biting' in a firm voice but I don't want him to think he can't 'love' people. At them moment I'm managing to head him off before he actually bites but I think I'm teaching him not to be affectionate. He's 13 months. Any thoughts, oh wise ones?
