My baby is always hungry and uses the breast as a dummy

[gcarravi]

I am breast feeding only my 3 weeks old baby, however he seems to be hungry all the time, or at least he asks for more every minute he is awake. If he has not my breast on his mouth, the he screams and cries like crazy. I think he is actually using my breast to confort himself as he hates the dummy and can´t still find his thumb. As a result my nipples are really sore. It is extremely painful. Can anyone tell me how to get my baby used to ask for the breast for feeding purposes only? Many thanks
