I suggest go to the activity forum and look up some schedules. I was really confused too, and had similar problems with my dd.
Very similar to in "Baby Whisperer Solves All Your Problems" I fed my dd four times a day. One waking, morning tea (on waking from 1st nap), afternoon tea (one waking from 2ndnap), then as a part of the bedtime routine.
My dd started to wake earlier (5.30am) around this time and I now wonder if I should have been offering her the breast after the meals. At the time I felt as though that would have been going backwards.
Good luck and hopefully there is a schedule that you think is right for you.
By the way my dd is now 10.5 and I've have those four feeds until just recently. I figured I may as well give dd the breast when I knew she would actually take it.
