Are you using a binkie? I just ask because it sounds similar to what I went thru with my baby and she was just wanting her pacifier. I sure do regret introducing it! Maybe a more isolated, quiet nursing place would help. I wonder if your baby is not receiving any milk. Sometimes my baby does that now when I am drained. She started eating solids WAAAY earlier than my first child because I wasn't keeping up my milk. I think dehydration has a big role to play in this for me. Be sure you're drinking enough, too! Are you eating anything that he might disagree with? (Maybe spicy, garlicky, foods, or something allergy-inducing.) Best of luck to you and your baby!
