Sounds like you are keen to hear of some light at the end of the tunnel without following the strict Ford schedule! But what other people's babies do, or don't do, does not have any direct relationship with what your baby will do - they are all so different. My babies started to sleep for longer stretches at an earlier stage than yours, but who knows what the reasons for the difference are.
One thing that most parents find is that the babies gradually go into a deeper sleep as they get older, and that seems to be a natural physiological thing. I forgot to put my 15 month old's pyjama bottoms on last night and was worried about her legs getting cold (she sleeps without bedding in the summer), so I sneaked in and managed to put them on her without waking her -to my great surprise! She has obviously learned to sleep more deeply lately.
You sound concerned that you are not doing things which contribute to your baby waking. I think babies' natures are so different, and the difficult ones will grow out of it eventually. It's a question of how desperate you are for change. The only things I would advise are to *sometimes* let your baby fall asleep in other ways than breastfeeding for *daytime* sleeps, and don't always run to her the moment she makes a sound. Sometimes they are just whimpering while they roll over and can go back to sleep by themselves. My baby sleeps much better when I forget to put the monitor on! (I can still hear her if she is very upset.)
Make sure you take naps or go to bed early while you have such broken sleep. Good luck for that longer stretch happening soon!
