Baby only sleeps when on my boob😧

Jeanette
I think Ive created a monster! My 3 week old only sleeps and relaxes when he's on my breast.. i think hes not even drinking, just nibbling and when i try to get up he'll bite down hard so i wont leave..he half breast feeds and half bottle feeds. I dont know what to do, he wont take a pacifier , and he'll cry and cry if i take him off me. I try to swaddle him, bounce him, swing, everything , he just wants a nipple 😧😧
