any advice please!!!

My 2 month baby uses my boobie as a pacifier to go to sleep 😩 i try  giving him a real pacificer but he spits it out...the problem is once he lets go and i try to lay him down on his crib he wakes up and starts crying and crying until i give in and give him back my boobie...is this just a bad habit??? Sometimes he doesnt even let me finish doing house chores becuz he just want to be there on the boobie even though  his done eating....and if i give him the pacifier he would cry and cry and cry dramatic even drop some tears and hold his breath until i pick him up and give it to him is that normal? Is anyone going through this? Is it gona go away once he gets more big??
