You certainly can! It is much easier if you don;t need to 'relactate' - ie if you have a newborn whilst still BF Jazz, but it can certainly be done and does as a matter of regularity.

There are so many resources on how to go about it, support forums and success stories.
I will get some link together for you, I have a whole bunch here somewhere. Will bbs.

Good on you for wanting to give it a go Leash!
