cherryale,
Don't worry lah. If you bf, you will have BM. Remember, it's a demand = supply thing. If you feed less, you will have less. So if you bottle feed, then try to latch on, then chances are, your bb will take less, and hence, you'll have less. Or if you latch on, then bottle feed, bb is very very full, will feed less often. Hence you will also have less.
