Pacifier?

Jaime
My baby is 6 week's old and I've been trying to give her a pacifier I really think she would benefit from one just to calm her down. When I put her down after breast feeding she kind of freaks out and cries so I put her on the boob again thinking she might still be hungry but she falls asleep 5mins later. Any tips I how to get her to like pacifiers or just tips on ways to help me from waking up once she isn't next to me?
