My baby is 6 weeks old. She doesnt really like pacifiers, she usually refuses it. But when she is very sleepy I try to put it in her mouth to calm her down and when she finally lets me put it in her mouth she will suck on it but then it falls out soon and then she cries for it so I have to keep putting it back in her mouth. Has anyone had this issue with a baby not being able to keep the pacifier in their mouth
