5 week old wants to suckle on me all the time! Help?

I have a 5 week old girl. Love her to pieces! I am breastfeeding with a bottle of breastmilk once a day after she nurses if she is still hungry. I do this because sometimes when she is done nursing she will Suckle on me for 30 min or more if I will let her. She will not continue to eat, just Suckle. For the past 3 weeks all she has wanted to do is have me in her mouth. She refuses to sleep on het cosleeper and instead of going every 2-3 hours between nursing I am lucky to get 1 hour. I cannot get anything done. A paci will not satisfy her but she needs to learn some other way of comfort besides me right? Do not say I am being cruel or this is what being a mom is about. Because every 30 min to an hour is to much. And she cannot be going through a 3 week growth spurt. How can I get her to stop using me as a pacifier? How can I get her to sleep on her bed? The moment she is down her eyes are open. She hates having her arms swaddled too so I only.do her lower body. Rocking doesn't work either. Help?
