Hi there, it sounds like you've been having quite the time with all this! When we taught our LO to self soothe and go to sleep in her crib (instead of on one of us) we used shh/pat and even after she fell asleep I would stay there with my hand on her chest for a few minutes. I don't know if this is "right" but it worked for us. We didn't have to keep it up for long - pretty soon we were able to put our LO down in her crib, tell her "sleep time", give her a kiss and leave, and now she puts herself to sleep. We do the same thing every time and I think she really appreciates the consistency.
I have had to feed my LO in the dark for about 2 months now, because of her getting distracted by every little thing! I don't think she looks at it as part of the wind-down, she just looks at it as getting food. But again, I think she appreciates the consistency of knowing when she is going to eat.
Honestly, our LO did not do well with suggestions from the BW until she was about 3 months old, and even then it was only bits and pieces that worked for her. We do a modified EASY that works for her and adjust as necessary because she is always changing. I used to stress and worry because she wasn't doing exactly what the book said she should be, but that's just the way our LO is, she is happy, she is healthy and that is all that matters to us. Good luck!
