Has anyone any tips on biting? My 16m ds starting biting when being breastfed(hence me stopping at 10m) and because i yelped in pain; he laughed.So, since then, he will bite for a reaction or loud ouch. He seems to do it also, as a sign of affection!!!I've tried not to give a reaction, but it's very hard(he has a very hard bite)Plus, he slaps people in the face!!? Do i have some kind of neanderthal, bully boy???!!
