I was never going to cope with NFs and a F/T job so from the get-go I did the old-fashioned tracy style "training" - DF EBM in a bottle from 10 days old with Oscar- the DF was the milk I pumped first thing in am so very fatty etc. We had him STTN (with DF of course) from 14 weeks consistently. He WAS prone to EWs and still is, but I preferred that anyway as I had to get up for work....
With Emma, I had much more significant low supply in the evenings and what I pumped in the am I used to settle her at 7pm, then could rest up till 11pm (or sleep) and would DF from the breast - DH brought her to me. She STTN consistently and well, without EWs, from 10 weeks!!! Such an angel!
Mine DID wake in the night but I'd offer the dummy - in the days that they were sleeping next to me in the Moses basket - and I never fed any closer to the DF than 3 hrs (so if DF 11pm, I never fed earlier than 2am). But by the 10 and 14 week mark we never heard a squeak from either of them till it was morning - honestly!
From what I know now after studying my bfing course etc and becoming an IBCLC I'd probably not be as "strict" with myself and their feeding, but that would also depend on when and if I was going back to work....with Oscar it was such a "stress" to get him STTN before 4.5 mths (as I was back in work at that stage). He did it fine but I remember thinking about it and wishing him to be born already to "start working on it" - he was born at 41+4 and I HAD to go back to work on a certain date so his being on the late side was eating into my time with him and my time sleep training him.....
I am just someone who does not survive the working day on broken sleep - even if it is for 5 or 10 minutes...and I had to do something about it early on....so I started with this "plan" from the outset. Don't know how it'd be if I hadn't. Probably in Emma's case it would have been a lot harder....as we had real supply and impatience issues from her!
