for me the benefit of DF was teaching my dd last longer between feeds at night - say, her last feed was at 19. Then I'd feed her round 22. So when she'd wake up at 1, i knew she was not hungry so I'd pat/sh her and wait for her next waking up, that time from hunger. worked for me. It took some 3 days to be able to move to something like E - 19, 22, 3 am, 8 am. and in some three weeks - E - 19, 23, 5 am. you could give a try and see what suits you best
cheers,
